UV Mapping in Cinema 4D

We know, it’s not the sexiest topic for a tutorial. But, if you’ve ever had trouble getting your textures to line up just right in Cinema 4D, this will help you out immensely.

UV mapping is one of those things that you can get by without for a while, but eventually you’ll run into a situation that requires it and you will REALLY impress people if you can do it. Your textures will improve a lot and you’ll have groupies chanting your name. One of those statements is true. 

So hang tight, and get ready to learn a TON of new info.

If you have any questions, click over to the Q&A tab to post them. Other students can answer you, and we'll put our team on the case to try and get you a solution ASAP. 

    • Why do my textures look smeared?

    • Your textures will smear if your UV islands are scaled incorrectly. Before applying any images in your texture map, try turning off all of the layers so you can see the checkerboard pattern underneath. Then, look on your model to see if the checkerboard is proportioned correctly. If it's not, that means you need to scale the UV islands until the checkerboard pattern looks correct. Also, make sure your UV island takes up enough space on the UV map to have the resolution necessary to stay sharp. You can also up the resolution on your texture map if you need.

    00:00:11,272- Well, hello.
    00:00:12,114Joey, here, for School of Motion,
    00:00:13,374and in this lesson,
    00:00:14,253we're gonna talk about something that most
    00:00:15,900Cinema 4D artists don't know how to do.
    00:00:18,130How to unwrap UVs in Cinema 4D.
    00:00:20,853What's a UV?
    00:00:21,910Well, you'll find out.
    00:00:23,206Knowing how to do this is essential
    00:00:24,973to creating precise textures in any 3D program.
    00:00:28,088This may not be the sexiest topic on earth,
    00:00:30,497but you're gonna wanna sit tight and take it all in,
    00:00:32,604because one day,
    00:00:33,915you're gonna run into a project where this is
    00:00:34,913going to save you a lot of trouble.
    00:00:37,225Don't forget to sign up for a free student account,
    00:00:39,348so you can grab the project files from this lesson,
    00:00:41,491as well as assets from any other lesson on this site.
    00:00:44,464Now, let's get started.
    00:00:46,697- [Narrator] So, I wanna start out by
    00:00:48,208showing you the way that I see a lot of new artists
    00:00:51,503apply textures in Cinema 4D.
    00:00:54,219So, I'm gonna start with the most basic 3D shape there is:
    00:00:57,225the cube.
    00:00:59,616Now, in order to
    00:01:02,238apply textures in a UV map way,
    00:01:06,055in Cinema,
    00:01:06,888you have to make the objects editable.
    00:01:08,835So, this cube right now, it's not editable.
    00:01:13,449It still has this object tab over here,
    00:01:16,154and I can adjust it and adjust segments, things like that.
    00:01:20,587But, if I click on the object and hit C,
    00:01:23,582it is now a polygon object, it has been made editable.
    00:01:28,077And you'll see that this little tag
    00:01:30,253has actually been applied automatically,
    00:01:33,272and it's called UVW tag.
    00:01:35,920Now, I'm gonna explain very shortly, what that is,
    00:01:40,197but for now, I wanna show you how
    00:01:42,528I started out learning Cinema,
    00:01:44,712and how I used to put textures on things like this.
    00:01:48,407So, I would double-click in this tab,
    00:01:50,370to create a new material.
    00:01:51,932And, you know, if you were doing something simple
    00:01:54,163like making a white cube,
    00:01:55,658you'd drag it on like this,
    00:01:57,260and there you go, there's your texture.
    00:01:59,072Now, what if I decided I wanted a picture
    00:02:01,777on this face of the cube?
    00:02:04,509So, but I still wanted the cube to be white.
    00:02:07,454So, what I might do is make another texture,
    00:02:10,992and in that texture,
    00:02:14,649I would load an image into the color channel.
    00:02:17,315So, let's go here,
    00:02:19,638and we'll go to My Desktop,
    00:02:22,837and I have found this very cute picture of a kitten,
    00:02:28,293and I wanna put that on the side of this cube.
    00:02:31,227So, what I usually do is,
    00:02:34,302I'll go into polygon mode,
    00:02:36,622select the polygon I want,
    00:02:40,116and then drag that material onto the cube, okay?
    00:02:43,732So, that's great,
    00:02:44,780all is well and good.
    00:02:47,443This actually looks okay,
    00:02:49,437but I can tell the image is actually being stretched
    00:02:52,418a little bit width wise.
    00:02:55,674So, by default, when you put a texture onto
    00:02:59,818a polygon, in Cinema,
    00:03:01,277it tries to scale that picture to fill the polygon,
    00:03:04,729and it doesn't pay any attention to
    00:03:06,667the actual aspect ratio of that image.
    00:03:10,534So, this kitten is actually supposed to be
    00:03:12,781a little thinner than this.
    00:03:14,379So, then you have to click on the texture tag here,
    00:03:19,367and start messing with the length,
    00:03:23,221and then you have to offset it,
    00:03:25,240try and get it to work,
    00:03:26,328and then you need to turn tiling off,
    00:03:29,449and so you end up having to kinda
    00:03:31,892do a lot of finagling to make this work.
    00:03:36,010And then, let's say I also wanted that image
    00:03:39,140on this face here,
    00:03:41,723so if I select that, and drag the kitten.
    00:03:47,394Alright, so what if I wanted the kitten
    00:03:49,069to be rotated 90 degrees?
    00:03:51,410Well, there's not really a great way to do that.
    00:03:53,917There are work arounds, and you could do it,
    00:03:55,720but really you don't have a lot of control with this method.
    00:03:58,591It's hard to get the texture you want
    00:04:01,224on the right faces.
    00:04:03,499So, that's where UV maps come in.
    00:04:05,508So, I'm gonna delete all of these texture tags.
    00:04:08,968Delete all these textures.
    00:04:12,460So, let me try to explain what a UV map is
    00:04:14,803to you guys.
    00:04:15,922And some of you may already know this.
    00:04:17,580But if you don't,
    00:04:18,741you're about to learn something that will make your life
    00:04:20,678so much easier once you get the hang of it.
    00:04:22,936So, the first thing I'm gonna do is
    00:04:25,465switch my Cinema layout from startup to BP UV edit.
    00:04:30,539BP stands for Bodypaint.
    00:04:33,129Bodypaint used to be a separate program from Cinema 4D,
    00:04:36,569and now everything is built right into the program,
    00:04:39,470and so the BP UV edit layout,
    00:04:42,661it brings up some new tools here.
    00:04:45,813And these tools are designed for UV mapping
    00:04:49,236and painting textures.
    00:04:51,035And, so on the left here,
    00:04:52,401you're seeing the 3D viewport,
    00:04:54,541which is the same as in the startup layout.
    00:04:57,653Over here, you are seeing the UV map,
    00:05:00,950for whatever object is selected.
    00:05:03,706And it will also show you the texture,
    00:05:05,486if you have a texture on that object.
    00:05:08,453So, if I click on this cube,
    00:05:11,037I'm gonna go into object mode here,
    00:05:13,564if I click on this cube,
    00:05:15,512and I go up to this menu here where it says UV Mesh,
    00:05:18,653and I hit Show UV Mesh,
    00:05:20,425you can see now, there's this one pixel
    00:05:22,948black outline around the entire frame.
    00:05:26,919So, this black outline is the current UV map
    00:05:30,886for this box.
    00:05:33,486And I'm gonna show you exactly what's happening.
    00:05:35,739So, the first thing I'm gonna do is create a material,
    00:05:37,737so I'm gonna double-click.
    00:05:39,088And you can see the material browser looks different now.
    00:05:41,930It's the same material browser,
    00:05:44,294it's just sort of arranged differently,
    00:05:46,698to make it more useful for Bodypaint.
    00:05:49,893Alright, and you don't really need to
    00:05:51,913know too much about the layout and
    00:05:54,235how all this works, just yet.
    00:05:56,365Just try and follow along.
    00:05:57,690And I will do more tutorials about Bodypaint,
    00:06:00,232because it's incredibly useful.
    00:06:02,186So, all I've done so far is created a material, alright.
    00:06:05,140Now, in order to actually paint in Bodypaint,
    00:06:09,901you actually need to load a bitmap texture
    00:06:12,704into at least one channel on your material.
    00:06:17,418So, this material here has a
    00:06:20,570color channel and specular channel.
    00:06:22,886Now, the color channel, right now,
    00:06:24,236it's just set to a color,
    00:06:26,075this kinda grayish, white color.
    00:06:28,835So, that's not gonna actually let me paint on this cube,
    00:06:32,536because there's no--
    00:06:33,974You need a bitmap to paint on to.
    00:06:36,750So, the shortcut to do that,
    00:06:39,631you can see here, next to my material,
    00:06:41,715there's a C.
    00:06:43,691That means that this material has a color channel.
    00:06:47,044Right below the C,
    00:06:48,214there's a little faint gray X,
    00:06:50,388and that means no image is
    00:06:52,480yet loaded into the color channel.
    00:06:54,418If I double-click that X,
    00:06:56,470it brings up this little menu
    00:06:58,524asking me to make a new texture.
    00:07:00,593Alright, so I'm gonna call this new texture box color.
    00:07:06,591The width and the height are both set to 1024 pixels,
    00:07:11,097which is 1K.
    00:07:12,538It's a very common size for textures.
    00:07:15,362And, this gray color is what the default color
    00:07:19,411of that texture will be.
    00:07:21,190So, why don't I set that to white?
    00:07:25,149You can see now that this area over here has turned white,
    00:07:28,481Because I have this material, and this channel selected,
    00:07:31,662it's actually loaded the bitmap, that I just created,
    00:07:35,122into the UV viewer over here.
    00:07:39,522Now, if I take this material, and drag it onto the cube,
    00:07:42,591you'll see the cube turns white.
    00:07:44,510Alright, so now we have a material on the cube,
    00:07:47,324we can see the cube's UV map, which,
    00:07:49,466right now, doesn't look like anything.
    00:07:51,318With the UV map right now, what it actually is
    00:07:54,519is every face of this cube
    00:07:58,622has been scaled to completely fill this UV space over here.
    00:08:03,649And, actually, it'll be easy to demonstrate if I--
    00:08:07,405I'm gonna grab the paint brush here.
    00:08:09,588And I'm gonna give it a red color.
    00:08:11,178If I paint anywhere on this,
    00:08:13,183you can see over here, I'm painting on
    00:08:15,901every single face of the cube at the same time.
    00:08:19,283Now, why is that?
    00:08:20,741Well, that's because this face and this face and this face,
    00:08:25,225have all been scaled up in their UV space over here.
    00:08:29,434So, this will make even more sense if I can
    00:08:33,181attempt to draw something close to a circle.
    00:08:36,987You can see that on this face,
    00:08:38,450it's stretched a lot horizontally.
    00:08:40,683Here, it's stretched vertically.
    00:08:45,184Here, it's stretched horizontally, too.
    00:08:46,479Here it's stretched a little bit more vertically.
    00:08:48,745It's much closer to this than this side.
    00:08:51,248And that's because a UV map is essentially
    00:08:57,011a way of wrapping a 2D texture,
    00:09:00,513which is what this is,
    00:09:01,827onto a 3D object.
    00:09:03,468And right now, all that's happening is
    00:09:05,049this whole texture is being mapped onto every face.
    00:09:08,808So, that's why you're seeing it on
    00:09:10,338every single side of the cube.
    00:09:12,156So, that would be useful only if
    00:09:16,032this was a perfect cube,
    00:09:17,487and you actually wanted the same texture on every side.
    00:09:21,210Which, most of the time, you don't want.
    00:09:23,460So, I'm gonna show you how to fix this.
    00:09:26,967So, if you look over here,
    00:09:29,293Bodypaint can be pretty confusing at first.
    00:09:32,637The bottom left hand side here,
    00:09:34,614has the Objects and Materials tab,
    00:09:37,156and it's also where you pick your color
    00:09:39,000when you're painting.
    00:09:40,914This center area is sort of,
    00:09:42,888this is the Attributes area,
    00:09:44,438so if you pick a tool, like a brush,
    00:09:46,654or you know, a selection rectangle,
    00:09:49,591you can set the settings here.
    00:09:51,240And then, on the right side,
    00:09:52,794these are all commands related to UV mapping,
    00:09:56,564but also to your textures and their layers.
    00:10:00,712Textures in Bodypaint can have layers
    00:10:02,780just like in Photoshop.
    00:10:05,290So, I have a background layer, here,
    00:10:06,551that now is white with this red circle on it.
    00:10:10,481So, I'm just gonna take my paint brush,
    00:10:13,750size it up,
    00:10:15,288and I'm gonna pick the white color,
    00:10:18,385and I'm just gonna erase this.
    00:10:22,413So, now we're starting from scratch.
    00:10:23,892So, the first thing I need to do is set
    00:10:25,083up the UV map for this cube.
    00:10:27,314So, when you want a UV,
    00:10:30,913when you wanna arrange UVs for an object,
    00:10:33,613you need to have that object selected,
    00:10:36,502you need to be in one of these UV edit modes up here,
    00:10:40,989where my mouse pointer is.
    00:10:42,951Bodypaint is very, very strict about
    00:10:45,388what mode you're in allowing you to do certain things
    00:10:49,907or not allowing you to do certain things.
    00:10:52,264So, in this UV mapping tag,
    00:10:54,907this is where you set up your UVs and
    00:10:57,373do a lot of operations about UVs.
    00:10:59,061And you generally start with the projection part.
    00:11:02,353This is where you kinda get started
    00:11:04,306unwrapping your 3D object,
    00:11:06,463and creating a map that you can then paint on.
    00:11:09,033You can see everything's grayed out right now.
    00:11:11,518That's because I'm not in one of these UV modes.
    00:11:14,435So, if I switch to this mode,
    00:11:16,777all of the sudden, these are all available to me.
    00:11:20,304And one thing you have to be very careful of is
    00:11:23,755when you have a polygon selection,
    00:11:26,709like I do here,
    00:11:27,625I have this top polygon selected.
    00:11:30,905If I do any of these operations,
    00:11:32,950it will only do it to that polygon.
    00:11:35,040So, I wanna make sure that I deselect all.
    00:11:41,305So, now I have the object selected,
    00:11:42,996I'm in one of these UV modes,
    00:11:46,489and I'm gonna hit the sphere button first,
    00:11:49,260just to show you what happens.
    00:11:51,947So, when I hit that,
    00:11:53,467it attempted to unwrap this cube
    00:11:56,924as if it was a sphere.
    00:11:59,064And that just has to do with the algorithms
    00:12:01,011that Bodypaint will use,
    00:12:03,008to try and unfold your 3D object
    00:12:05,772into a 2D sort of plane, here.
    00:12:09,542Think of it like origami,
    00:12:11,177it's trying to unwrap an origami object.
    00:12:14,571Obviously, this doesn't do us much good,
    00:12:17,944because I don't know which face is which,
    00:12:20,998and there's this weird line over here,
    00:12:22,511and that's clearly not what we want.
    00:12:24,434If we hit cubic, it looks very similar to where we started,
    00:12:29,267where we have a bunch of overlapping squares.
    00:12:32,468That's not what we want, either.
    00:12:34,511Cubic 2, now this is much closer.
    00:12:37,762And you may actually think that this is correct.
    00:12:41,206Because you can now see that every face of this cube
    00:12:44,602clearly has its own UV area that you could paint on.
    00:12:49,665And, it looks like a box that's been unfolded,
    00:12:53,722like an origami box.
    00:12:55,111So, that's what we want.
    00:12:56,656However, this isn't right, and I'll show you why.
    00:12:59,886If you go into your layers,
    00:13:01,182and you turn the background visibility off,
    00:13:03,378there's gonna be a checkerboard pattern that shows up here.
    00:13:07,858And sometimes,
    00:13:09,426in order to get the 3D view to update,
    00:13:11,606you have to move the camera around a little bit.
    00:13:13,274So, this checkerboard pattern is
    00:13:15,198made up of perfect squares.
    00:13:16,958And this is useful,
    00:13:18,304because if you now look at your 3D object,
    00:13:21,338if you don't see perfect squares,
    00:13:23,244which we clearly don't, these are stretched out,
    00:13:25,408that means that your UVs are not proportionate
    00:13:29,723to the polygons that they're actually representing.
    00:13:33,285So, this is gonna make it a lot harder to paint,
    00:13:36,267because if I want a perfect circle
    00:13:40,182on the top of the box here,
    00:13:41,778and now that we have the UV set up,
    00:13:43,760you can start to see how cool this is.
    00:13:45,415If I move my paint brush over the top in the 3D view,
    00:13:49,826it also shows up in the UV view, and vice versa.
    00:13:53,087So, if I wanted to paint a perfect circle,
    00:13:55,304it'd be really nice to just be able to
    00:13:57,726pick a color and then come over here and
    00:14:00,508paint a circle like this.
    00:14:02,150But, you'll see on our 3D object,
    00:14:04,259it's actually not a circle.
    00:14:06,108And that's because this UV area here, was squared
    00:14:10,718instead of actually made proportionate to the right size.
    00:14:15,717So that didn't work either.
    00:14:17,293So we're gonna, with our cube selected,
    00:14:20,278go back to one of the UV modes,
    00:14:22,271go to UV Mapping Projection, and hit Box.
    00:14:26,633Now, what Box does, is it does something similar to Cubic,
    00:14:30,265except it actually maintains the correct proportions.
    00:14:34,575And so you can see now,
    00:14:35,936if I turn this off and move this around,
    00:14:39,710we now have perfect squares all over our cube.
    00:14:44,114And this is wonderful, for many reasons.
    00:14:48,143So, this is now clearly useful,
    00:14:51,810because you can take a paintbrush and paint
    00:14:56,860right on this image,
    00:14:58,973and it will show up exactly the way you paint it
    00:15:02,442on your 3D object.
    00:15:04,458Or, you can paint right on the 3D object too,
    00:15:07,481and it will paint over here.
    00:15:09,066Alright, so if you wanna come in,
    00:15:11,169and if you're good at painting,
    00:15:13,011then you can get some really cool results doing this.
    00:15:16,932And this is really useful, too,
    00:15:19,761you can see, for example, here.
    00:15:23,676I can paint along this edge and get a seamless result.
    00:15:28,166And over here, it's actually painting here
    00:15:30,589and here, at the same time.
    00:15:32,605So, a lot of times, when you're texture painting,
    00:15:34,484you have to kinda use a combination of
    00:15:36,386the 2D texture map, and also the 3D object itself
    00:15:40,650so you can sort of paint over these seams.
    00:15:45,075So, this isn't very interesting looking,
    00:15:46,607it actually looks kinda silly.
    00:15:48,013So, I'm gonna stop.
    00:15:49,215So, let me clear out this background.
    00:15:53,541So, I'm gonna select a white color,
    00:15:55,971and I'm gonna go edit,
    00:15:57,711fill layer,
    00:15:58,755so now I've filled my background with white again.
    00:16:02,148So, one of the coolest things you can do now,
    00:16:05,427if you have your object selected
    00:16:07,481in one of the UV modes,
    00:16:09,567you can come up here to Layer,
    00:16:11,277and there's an option right here that says
    00:16:13,801Create UV Mesh Layer.
    00:16:16,781So, what this does is
    00:16:18,190it actually creates an image of this UV mesh layer.
    00:16:22,435So, when I earlier turned on show UV mesh,
    00:16:26,899and this is again, an example of Bodypaint being finicky,
    00:16:30,537in order to turn this on or off,
    00:16:32,908you have to be in an object mode, not a UV mode.
    00:16:36,010So, you have to go back to UV Mesh, Show UV Mesh.
    00:16:38,792So, UV mesh is off, right?
    00:16:40,712And we have this UV mesh layer
    00:16:42,585because my paint color was set to white,
    00:16:45,935my UV mesh layer is white.
    00:16:49,083And it looks a little funky,
    00:16:50,379it's just cause I'm zoomed out.
    00:16:51,633If I zoom in, you can see its actually created outlines
    00:16:55,811of my UV.
    00:16:58,216And I think I can actually
    00:17:03,073invert this.
    00:17:06,625Let me try and turn this black.
    00:17:11,347There we go.
    00:17:13,703Alright, so now we've got a white background
    00:17:15,538with these nice black lines
    00:17:17,988that represent our UV map.
    00:17:23,235what's great about this is that now I can come up to
    00:17:25,903File, Save Texture As,
    00:17:29,236and you can actually save textures right outta Bodypaint
    00:17:31,594as Photoshop files.
    00:17:34,289So, I'm gonna save this as box color,
    00:17:37,490in my nifty little folder.
    00:17:41,231I'm gonna go over to Photoshop now, and open that.
    00:17:49,568Alright, so now we have the texture open in Photoshop,
    00:17:52,532and this UV mesh layer,
    00:17:54,513we can turn on and off
    00:17:57,358to show or hide where our polygons are.
    00:18:01,677And, in Photoshop, you know,
    00:18:04,307I'm a lot more comfortable in Photoshop.
    00:18:06,084A lot of things you do in Photoshop can be done
    00:18:08,021in Bodypaint, but I generally work in Photoshop because
    00:18:10,858I'm really fast at it, I know it a lot better.
    00:18:13,364But, what I'm gonna do is open up this image I found,
    00:18:18,344which is kinda this cool looking crate ottoman,
    00:18:23,191and I'm going to cut out the front of this
    00:18:34,118Just like that.
    00:18:41,839And paste it in here.
    00:18:44,066Alright, now it's clearly skewed.
    00:18:49,186So, I'm gonna try to,
    00:18:52,221try to straighten it out as best I can.
    00:18:57,880It's close enough for now.
    00:18:59,279And then what I'm gonna do
    00:19:00,628is I'm gonna scale this down
    00:19:02,833and I'm gonna line this up.
    00:19:13,881Like that.
    00:19:16,446And then I'm gonna,
    00:19:18,605I'm gonna come in here and I'm just gonna,
    00:19:21,624just kinda manually adjust
    00:19:25,779so it fits a little better.
    00:19:28,281Now, you probably are already starting to see
    00:19:30,227the benefit of doing texturing this way.
    00:19:33,066I have complete control over
    00:19:35,374exactly what image goes in here,
    00:19:37,771if I wanted to rotate it,
    00:19:38,954I would just rotate it like that.
    00:19:41,045If I want to adjust levels on just that piece,
    00:19:43,364I can.
    00:19:46,445And I could call this
    00:19:48,193Side one,
    00:19:51,021save this Photoshop file,
    00:19:52,590and then I can turn the UV mesh layer off,
    00:19:54,844save one more time.
    00:19:55,988And now, if I go back into Cinema,
    00:19:58,581come up to File and say Revert Texture to Save,
    00:20:02,556it will say, "Do you really want to revert?"
    00:20:04,423Yes, you do.
    00:20:06,075What it's doing is reopening the texture
    00:20:08,216that I've modified in Photoshop,
    00:20:09,875and it's reopening it in Cinema.
    00:20:11,998And it has the same layer setup as Photoshop,
    00:20:15,452here's my UV mesh layer, which was turned off.
    00:20:17,932And here's side one.
    00:20:19,551And if we spin this box around,
    00:20:21,641we can see there is side one.
    00:20:24,732One thing I'm gonna change really quickly,
    00:20:27,429in my material,
    00:20:28,804you can see how the preview of this material
    00:20:31,288is very low res, and kinda grungy.
    00:20:35,162That's cause this is a 1K texture,
    00:20:39,391but Cinema, by default, doesn't preview textures at 1K.
    00:20:43,407And you can change that if you click on a material,
    00:20:46,461and you go to Editor,
    00:20:48,802texture preview size is default right now,
    00:20:50,793I'm just gonna turn that up to 1K.
    00:20:52,756So, now I can actually see a pretty
    00:20:55,233high-quality preview
    00:20:56,964of what that texture looks like.
    00:21:00,406So, now, I could go back into Photoshop,
    00:21:02,567and line up the other sides.
    00:21:05,339You can also do this directly in Bodypaint.
    00:21:09,615You can take this layer here,
    00:21:12,936and you can,
    00:21:14,299all these buttons down here,
    00:21:15,541make new layers,
    00:21:16,753make copies of layers, delete layers.
    00:21:17,994So this,
    00:21:18,827this button with the yellow square
    00:21:20,086on top of the white square,
    00:21:21,229makes a copy of whatever layer you have selected.
    00:21:24,033So, I could call this Side two.
    00:21:26,307Grab the move tool.
    00:21:28,694And just move this over to the next square.
    00:21:33,225And you can see, in real time,
    00:21:36,021what you're doing, too.
    00:21:37,177Which is pretty cool.
    00:21:40,492So, you can go through and line all of these images up,
    00:21:45,396or you can find different images and put them on top,
    00:21:48,919and make this look like whatever you want.
    00:21:50,898And, I'm not gonna go into detail about
    00:21:53,982what different texture channels you want
    00:21:57,165to make this look real,
    00:21:58,515that's for another tutorial.
    00:22:00,028But, hopefully this shows you,
    00:22:01,928you know,
    00:22:03,290the benefit of taking the time
    00:22:05,182to set up a proper UV map.
    00:22:07,377You can have layers,
    00:22:09,982you can even clone stamp if you,
    00:22:12,573you know, if you wanted to,
    00:22:15,711let's say just real quick,
    00:22:17,229if I copied this layer and I moved it over here,
    00:22:21,030and I just wanted to stretch it to fit the top,
    00:22:27,270like that.
    00:22:31,127So, now we've got this side
    00:22:32,588wrapping around to this side and this side.
    00:22:35,174You know, if I'm looking--
    00:22:38,167Sorry, I'm hitting the wrong button.
    00:22:40,415If I look at the seam here,
    00:22:47,615I'm seeing some white pixels here.
    00:22:49,631There's probably some image area here
    00:22:52,021that needs to be cleaned up.
    00:22:54,161You can actually add a new layer,
    00:22:56,992grab the clone stamp,
    00:22:58,716set the clone stamp to All Visible Layers,
    00:23:00,697and you can actually use a clone stamp
    00:23:03,035on the seam here.
    00:23:05,066And you know, grab a piece of image
    00:23:08,019and paint it in,
    00:23:09,621and sorta work on the seams this way, too.
    00:23:13,143And then, once you,
    00:23:14,731if you know a little bit about painting,
    00:23:17,550or if you just wanna kinda mess around,
    00:23:20,237sometimes, especially on 3D objects,
    00:23:22,616it's cool to beat up the edges a little bit.
    00:23:25,546And it's really easy to do that
    00:23:28,171with this method.
    00:23:29,199So, you could add a new layer.
    00:23:31,393You could pick a color.
    00:23:33,504Let's say you wanted to just
    00:23:34,862add a little bit of a highlight to this or something,
    00:23:37,501you could pick,
    00:23:39,586maybe pick a color from the texture itself,
    00:23:42,388to use as a highlight color,
    00:23:45,413and you can turn the opacity way down on this layer,
    00:23:48,648and just kinda come in and just,
    00:23:52,916and just paint it a little bit.
    00:23:59,103And you can see, you just kinda get this grungy,
    00:24:01,917this grunginess to it.
    00:24:03,033And then you can take this layer,
    00:24:04,327once you're kinda happy with the general shade,
    00:24:06,010you can blur it a little bit.
    00:24:07,868You can come up to Filter and you can,
    00:24:10,435you can add a little bit of a blur,
    00:24:14,451and you can see what it's doing.
    00:24:17,694And you can see,
    00:24:18,939here's before and after.
    00:24:21,371And it just adds like, a little highlight,
    00:24:23,151and it kinda marries these two edges together.
    00:24:26,228And if I render this,
    00:24:29,625going back into Object Mode, here.
    00:24:33,614You know, you can see you're starting to get,
    00:24:35,229kinda looks like a computer game crate right now,
    00:24:38,948but you can see that with some work,
    00:24:41,131you could actually get a really nice result doing this.
    00:24:44,108So, that's part one.
    00:24:45,975I showed you how to unwrap and texture a box.
    00:24:49,986A box is about the simplest object you would
    00:24:52,503ever be asked to texture,
    00:24:53,763but the good thing is now you know how to do it.
    00:24:55,779The next thing I'm gonna show you,
    00:24:57,220as quickly as I can,
    00:24:58,789is how to unwrap an object that's
    00:25:00,626much, much, much more complicated than this box.
    00:25:04,887I took an object,
    00:25:07,443and I'm gonna switch my layout back to startup for a minute.
    00:25:10,752So, this object actually comes with Cinema 4D R13,
    00:25:14,138which is what I'm working in.
    00:25:16,297And I removed all of the
    00:25:18,205you know, other objects around it,
    00:25:20,347his eyes, his pants, his hat, things like that.
    00:25:23,265So, we can just focus on the body and the head
    00:25:25,887of this kinda alien looking guy.
    00:25:28,658And actually, the body and the arms and everything
    00:25:31,812are inside of HyperNURBS,
    00:25:33,809so I'm gonna turn that off for a minute,
    00:25:35,665so we can see the mesh.
    00:25:37,640Alright, so here's your mesh.
    00:25:38,869Now, if you wanted to try and put a face here,
    00:25:42,178and a shirt on him,
    00:25:43,922and fingernails and things like that,
    00:25:46,208there is no way you could do that
    00:25:48,473without getting a clean UV map of this.
    00:25:52,938It won't even be possible because the UVs,
    00:25:57,122if they're overlapping,
    00:25:58,652you're never gonna be able to paint accurately,
    00:26:01,413and you're never gonna get the resolution you need
    00:26:03,428with your texture maps.
    00:26:05,086So, unwrapping something like this,
    00:26:07,395is a really good thing to practice,
    00:26:09,711because if you can unwrap this,
    00:26:11,402you can unwrap just about anything.
    00:26:14,565So, let's start by trying to get a good UV map
    00:26:18,580for the head of this.
    00:26:21,328So, let's go back to BP UV Edit Layout.
    00:26:24,799I'm gonna take the--
    00:26:27,117I'm gonna leave the HyperNURBS off,
    00:26:28,380because that will just make it confusing.
    00:26:30,426So, with my body object selected,
    00:26:33,383I'm in Object Mode right now,
    00:26:35,235I'm gonna turn on Show UV Mesh.
    00:26:39,141And, you can see there's actually no UV mesh,
    00:26:41,732and that's because there's no UV tag
    00:26:44,328on the body object.
    00:26:46,587That little checkerboard tag that showed up
    00:26:48,557when we put texture on, on the cube,
    00:26:50,024that is actually the tag that stores the UV information,
    00:26:53,737and without that, you can't actually unwrap or do anything
    00:26:57,212to an object.
    00:26:58,891So, the quickest way to get a UV tag is to just
    00:27:01,792make a new material,
    00:27:03,719put it on the object,
    00:27:05,395and you can see immediately, UVs showed up over here.
    00:27:11,046now with the object selected,
    00:27:12,882I'm gonna go into UV mode,
    00:27:15,748and go to the Projection tab.
    00:27:18,145Now, you can see that the
    00:27:19,467Projection tab is still grayed out,
    00:27:22,116and that's because there actually is no UV tag over here yet
    00:27:26,544and that is because,
    00:27:28,484when I applied the texture,
    00:27:31,260because there was no UV tag on the object,
    00:27:33,917the texture defaulted to spherical projection,
    00:27:37,901instead of UV.
    00:27:39,716So, what you have to do in this situation,
    00:27:41,522is control+click or right click
    00:27:45,495the texture tag,
    00:27:47,345and hit Generate UVW coordinates,
    00:27:49,486and it will create a UV tag,
    00:27:52,604and now you can actually start working with UVs.
    00:27:56,236So, I'm gonna make sure I don't have any polygon selected,
    00:27:59,802I'm gonna go Select Geometry, Deselect All.
    00:28:03,720And, I'm just gonna show you why this is tricky.
    00:28:07,451If I try these projection settings here.
    00:28:10,938So, Sphere makes a mess out of it.
    00:28:14,069Cubic makes a much worse mess.
    00:28:17,841Cylinder, you can actually kinda tell what's going on,
    00:28:20,874this is the head, these are hands.
    00:28:22,652But, the biggest problem with UVs like this is that
    00:28:26,359all of these UV polygons here,
    00:28:29,417they're overlapping each other.
    00:28:31,007So, if I drew a line here,
    00:28:33,581it would wrap all the way around the arm,
    00:28:35,485and that's not what we want.
    00:28:37,161And you can see that none of these really
    00:28:39,514give us what we need.
    00:28:41,029So, with an object like this,
    00:28:42,451you have to do a little bit more work.
    00:28:44,415So, the best way to start is to
    00:28:46,135break the object into manageable pieces.
    00:28:49,237So, we're gonna start with the head.
    00:28:51,356So, what we're gonna do is
    00:28:52,900first select all the polygons of the head.
    00:28:54,599So, we're gonna go into Polygon Mode, up here,
    00:28:59,125and I'm gonna use my lasso selection.
    00:29:02,229Make sure you have Only Select Visible Elements turned off.
    00:29:07,810And then, we can just select all of these polygons.
    00:29:12,778Alright, and you see we've got this little neck,
    00:29:15,315all the way up into the head,
    00:29:16,445everything's selected, it's nice.
    00:29:18,249So now,
    00:29:22,747usually when I do UVs,
    00:29:25,677I first wanna clear what's already in here,
    00:29:31,018because it'll start to get messy, otherwise.
    00:29:33,165So, I'm gonna quickly undo what I just did.
    00:29:35,253I'm gonna select every polygon,
    00:29:39,997switch to UV mode,
    00:29:41,420and then come over here to UV Commands,
    00:29:43,496and hit Clear UV.
    00:29:45,284And it will,
    00:29:46,393you can see what it actually did.
    00:29:47,614It took all of the UVs, and it scaled them down to zero,
    00:29:50,098and stuck them up in the corner,
    00:29:51,502kinda hide them away for you.
    00:29:54,200Alright, so now I'll come back here,
    00:29:55,714select the head and neck again.
    00:29:59,342Didn't get the neck that time.
    00:30:02,787There we go.
    00:30:04,781And I'm going to use Frontal Projection
    00:30:07,811to get us started, here.
    00:30:09,880So, I'm gonna go to the Projection tab,
    00:30:12,161make sure I'm in a UV edit mode here,
    00:30:15,400and I'm gonna hit,
    00:30:17,258I just selected the arms by mistake,
    00:30:19,015I'm gonna hit Frontal.
    00:30:21,857Now, what its actually done is its
    00:30:24,793projected the UVs from the top view,
    00:30:29,083which is not what I wanted,
    00:30:30,261so I'm gonna hit Undo.
    00:30:31,670Whichever view is active, when you hit Frontal,
    00:30:34,928that's the view that Bodypaint will use to project the UVs.
    00:30:39,301So, I wanna make sure I'm looking at the front view,
    00:30:41,674because the reason I'm doing it this way
    00:30:43,835is because when I'm painting a face,
    00:30:45,741it's easier to paint that face when you're looking
    00:30:47,490straight at it.
    00:30:48,930So, that's the direction I want the UVs to be facing.
    00:30:52,374I don't want the UVs oriented like,
    00:30:55,424you know, the character's facing sideways.
    00:30:57,802I want to see the face laid out flat for me.
    00:31:01,333So, all I need to do is click on
    00:31:04,424the bar above Front View,
    00:31:05,880so now it's selected,
    00:31:06,906now when I hit Frontal,
    00:31:08,527you can see that this UV layout matches this
    00:31:12,526Now, we still have all of these UVs overlapping,
    00:31:15,675because obviously we're seeing the front
    00:31:17,697and the back of the object at the same time.
    00:31:20,444So, the next step,
    00:31:22,498is to take these polygons and unfold them.
    00:31:26,648And that is called relaxing the UV.
    00:31:30,313Now, when you do this,
    00:31:33,757if you think of this head as an origami object,
    00:31:37,358you need to somehow unfold it.
    00:31:39,830Well, the only hole in that object,
    00:31:44,379where you could actually unfold anything,
    00:31:46,432right now, is this neck.
    00:31:49,166So, Bodypaint doesn't know how you want this unfolded.
    00:31:52,928It's not smart enough to know that this is a face,
    00:31:55,311and this is the front of the face,
    00:31:57,015or anything like that.
    00:31:58,157You have to give it a hint.
    00:32:00,965So, the way you do that is,
    00:32:03,423you tell it which edges it should cut,
    00:32:07,350and then try to unfold the object.
    00:32:10,099And this takes a little practice to do,
    00:32:13,829but once you get the hang of it,
    00:32:15,455it starts to make a lot of sense.
    00:32:17,615So, if we wanna--
    00:32:19,403We basically wanna be able to
    00:32:20,758paint on the front of the face,
    00:32:22,690all is one piece,
    00:32:23,676so we're not gonna cut here.
    00:32:25,545And generally, you try to make as few cuts as possible,
    00:32:29,162and try to place the cuts in areas that are not as visible.
    00:32:34,122So, for a head, it's usually the very back of the head.
    00:32:38,528So, to do this, I usually like using the
    00:32:40,892Path Selection Tool,
    00:32:42,686if you hit U to bring up the Selection Menu,
    00:32:46,596and then the command we're looking for is Path Selection,
    00:32:52,838which is M.
    00:32:54,271So, U, M.
    00:32:55,520Alright, so I'm gonna start down here,
    00:32:58,467at the bottom of the neck,
    00:32:59,672and the UVs actually start one polygon up here,
    00:33:03,757but it doesn't matter for this purpose.
    00:33:05,862So I'm gonna just start tracing this edge.
    00:33:08,881And the Path selection tool basically just lets you draw
    00:33:13,264from one point to the next.
    00:33:14,649And I'm holding shift to continue my path.
    00:33:19,142And I'm gonna go all the way up,
    00:33:20,862and I'm gonna stop at the top of the head.
    00:33:24,671So, now we've got a nice seam in the back.
    00:33:27,262So, imagine that when I hit Relax,
    00:33:29,889it's going to peel the head open,
    00:33:32,662you know, like an orange or something,
    00:33:34,353and then it's going to unfold the face flat,
    00:33:36,404or it's going to attempt to.
    00:33:38,205Alright, so now I have an edge selected.
    00:33:40,659I have the beginnings of my UV map,
    00:33:42,475so I'm gonna go back into a UV edit mode.
    00:33:44,816And now I'm in the Relax UV tab
    00:33:49,452and you have a few options here.
    00:33:53,014And you wanna make sure that Cut Selected Edges is checked.
    00:33:57,782And that's actually what's gonna tell Bodypaint
    00:34:00,940look at what edges are selected, and then place cuts there.
    00:34:03,938This LSCM versus an ABF option,
    00:34:08,010these are just slightly different
    00:34:09,999algorithms that it can use to unfold,
    00:34:11,961and I don't really know what the difference is.
    00:34:14,109I'll try one and then I'll try the other
    00:34:15,787and see which one works better.
    00:34:17,494So, I'm gonna hit apply,
    00:34:19,574and you'll see we've got a very strange result here.
    00:34:22,750I think that is because,
    00:34:24,258I'm gonna undo,
    00:34:25,091I have Pin Border Points checked,
    00:34:27,281which I shouldn't have had checked.
    00:34:29,226So I apologize.
    00:34:30,468So make sure that that's unchecked.
    00:34:33,560Not exactly sure what that does either,
    00:34:35,441but it clearly messed up our result here.
    00:34:37,844So, now with that unchecked, I'll hit apply.
    00:34:40,337Lo and behold, look at what we have here.
    00:34:44,099Now, this may not make a ton of sense,
    00:34:47,424right off the bat, looking at it.
    00:34:50,232But, I'm gonna show you why
    00:34:51,741this is now incredibly useful to us.
    00:34:54,758So, the first thing I wanna do is
    00:34:56,532orient this a little better.
    00:34:58,006You can tell that it's kinda slanted.
    00:35:00,297It's probably clear that this is the face,
    00:35:03,739and these are probably the eye holes right here,
    00:35:06,730and this is the neck down here.
    00:35:08,561So I want this to be facing straight up.
    00:35:11,891When you're in one of these UV edit modes,
    00:35:14,552you can use the same keyboard shortcuts you can
    00:35:17,833to transform models and other objects
    00:35:22,125in Cinema 4D.
    00:35:23,416The hotkeys that I use are the 4, 5, and 6 keys.
    00:35:27,228If I hold 4, I can move this.
    00:35:30,066If I hold 5, I can scale it.
    00:35:32,082If I hold 6, I can rotate it.
    00:35:34,023So, I'm gonna rotate it until it's more or less straight.
    00:35:39,659Alright, close enough.
    00:35:40,884Alright, so now,
    00:35:44,133here is our head UV mapped.
    00:35:46,484Let's scale it down a little bit.
    00:36:00,823There we go.
    00:36:03,917Good to go.
    00:36:04,750Alright, so now,
    00:36:06,616we need to--
    00:36:10,057we need to do the same setup for this texture,
    00:36:14,412that we did for the one for our box.
    00:36:16,100We need to create a bitmap
    00:36:17,712to paint on
    00:36:18,870to be able to see anything happen
    00:36:20,861when we try to paint on this texture.
    00:36:23,483So, there is a color channel on this material,
    00:36:25,634but there's no bitmap in it,
    00:36:27,148so I'm gonna double-click under here,
    00:36:30,047and also you'll see this red X next to the material,
    00:36:33,376means that the material is not loaded into memory.
    00:36:36,276So you have to click that X to load it,
    00:36:38,825and then double-click under the C.
    00:36:42,700Again, Bodypaint is so finicky,
    00:36:44,492if you forget one step, it doesn't do what you need.
    00:36:47,522So, you'll have to do this 20 times before
    00:36:49,874you'll stop forgetting things.
    00:36:51,833And even then, you'll forget things.
    00:36:53,466Cause clearly, I still do.
    00:36:55,433So, instead of a 1K texture,
    00:36:56,983why don't we do a 2K texture, here.
    00:36:58,846So, we'll do 2048
    00:37:01,453by 2048.
    00:37:05,280And let's make the skin a little alien color.
    00:37:08,896Maybe like a,
    00:37:10,091kind of a yellowish-brown-green.
    00:37:14,777Alright, now if we come in here,
    00:37:17,518and I'm gonna add a new layer to this texture.
    00:37:21,542And I'm gonna pick a color, maybe I'll pick white.
    00:37:25,801So now, as I move the brush around here,
    00:37:28,415you can see on the model that we have a nice,
    00:37:33,058pretty nice symmetrical UV map here.
    00:37:36,977And, if I wanted to bring this into Photoshop,
    00:37:41,260and find some leathery texture to make the skin,
    00:37:44,938and then, find some weird creature eyeballs,
    00:37:48,846and nostrils and things like that,
    00:37:50,813I could do that.
    00:37:51,915It would be kinda tricky right now because,
    00:37:54,781I'm not really given much of an idea.
    00:37:57,609Like, where's the nose, where's the mouth, things like that.
    00:38:00,933So, what I usually like to do
    00:38:02,467before I send this to Photoshop,
    00:38:03,692is create some guides for myself.
    00:38:06,391So, I'm gonna go over to the Objects tab,
    00:38:08,954and I'm gonna turn the HyperNURB back on.
    00:38:12,064Because that really affects the look of the alien
    00:38:15,495quite a bit.
    00:38:16,499And you can see I can still paint
    00:38:18,183on the object or on the UV and still see what it's doing.
    00:38:21,370So, let's say I want the nose to be something like that.
    00:38:27,445Now I have a guide of where the nose is.
    00:38:30,741The eyes are a little more obvious.
    00:38:32,683But if I wanted, let's say, eyebrows or something,
    00:38:36,919and then a mouth,
    00:38:38,720you know, do you want the mouth down here,
    00:38:41,019do you want it a little closer to the nose,
    00:38:43,076maybe there?
    00:38:45,153And then let's say that, you know, you were gonna have
    00:38:48,161hair on this alien for some reason,
    00:38:50,970it's not obvious from this where the hairline is,
    00:38:53,726so it's always a good idea to kinda give yourself
    00:38:58,977some help,
    00:39:01,178so you know where the hairline's gonna be.
    00:39:10,750(laughs) And you can see it's very uneven,
    00:39:13,042so you have to kind of, you know,
    00:39:14,858this is a rough guide.
    00:39:15,983This is more of a suggestion than anything else.
    00:39:20,499Anyway, so you can see now that all of this area here,
    00:39:24,732this is all the hair,
    00:39:29,891and I know where the eyes are,
    00:39:32,833you can even paint those in if you want.
    00:39:35,070You know where the eyebrows are,
    00:39:36,436the nose, the mouth,
    00:39:37,403you have guides for everything.
    00:39:38,661And if you wanna know, you know,
    00:39:41,337this is the neck,
    00:39:42,170it's pretty obvious this is where the neck is,
    00:39:45,145but if you wanted to know exactly where the neck is,
    00:39:48,503you could just kinda draw a line there.
    00:39:51,269And on your UV you can see that
    00:39:53,598the lines I'm painting,
    00:39:54,974they follow the contour of these polygons.
    00:39:58,546So, now you know that's the neck.
    00:40:00,823Alright, so now you have a pretty decent
    00:40:03,058map that you could bring into Photoshop.
    00:40:05,943You could obviously use the same trick where
    00:40:09,139you would go up to Layer,
    00:40:10,663and say Create UV Mesh Layer.
    00:40:12,502Save a Photoshop file,
    00:40:13,882and bring that into Photoshop,
    00:40:15,242and then create your alien texture,
    00:40:17,730and reload it in Cinema,
    00:40:19,743and be good to go.
    00:40:21,033So, now that we have the head,
    00:40:22,780I'm gonna delete this for now,
    00:40:26,834let's get the body unwrapped.
    00:40:28,790The body's gonna be a little bit trickier, alright?
    00:40:31,096So, what we need to do is first select all the polygons
    00:40:34,187of the body and the hands.
    00:40:37,122So I'm gonna go into polygon mode here,
    00:40:39,350I'm gonna turn the HyperNURBs back off,
    00:40:41,813and I'm gonna hit Command+A to select everything.
    00:40:45,516Now, we don't what the head selected.
    00:40:47,524So, what I can do is go back into UV polygon mode.
    00:40:52,852And you can see that,
    00:40:54,113in that mode, I can see which UVs are selected, as well.
    00:40:57,547If I hold Command and draw a selection box around this,
    00:41:02,064it will deselect those polygons.
    00:41:04,684So I've deselected the head, now.
    00:41:06,438So, I now just have the body selected.
    00:41:11,514Now, I think for the hands and the arms,
    00:41:15,206it'll be a little bit easier to, you know,
    00:41:18,613it'd be easier to paint the hands looking down at them
    00:41:21,681than looking at this angle.
    00:41:24,956So, I'm gonna start my projection from the top view.
    00:41:29,706So, I'm making sure that my top view is active.
    00:41:32,297I'm in a UV mode, my body is selected,
    00:41:35,637and I'm gonna go to UV mapping projection,
    00:41:38,264and hit Frontal.
    00:41:40,260And now, you can see its put those UVs directly
    00:41:42,690on top of the face,
    00:41:43,630so I'm gonna hold down 4,
    00:41:45,018and I'm gonna move that down like this.
    00:41:47,550Now, it's going outside the boundaries
    00:41:49,406of the UV map,
    00:41:51,026that's okay for now,
    00:41:52,131we can always shrink down.
    00:41:54,497So, now, this is a good start.
    00:41:55,984But obviously, we have tons of overlapping polygons,
    00:41:58,592and this is a very complicated shape.
    00:42:01,411So, we need to cut some edges and let Bodypaint
    00:42:05,215unfold this again.
    00:42:08,506So, unwrapping characters is something
    00:42:13,292that takes a lot of practice.
    00:42:15,944And, to be honest, I'm not very good at it.
    00:42:18,304I don't do it a lot.
    00:42:20,598But, it's one of those things where
    00:42:22,438once you do it a a couple times,
    00:42:24,645it's kinda always done the same way.
    00:42:28,357I've seen hands done a couple of different ways.
    00:42:31,706And the way I'm about to show you is pretty useful
    00:42:36,193if you really wanted a lot of detail in the hands.
    00:42:39,593This will make it pretty easy to paint them.
    00:42:41,721However, there are better ways,
    00:42:44,064and you can always make it easier on yourself by
    00:42:46,562doing the hands separately.
    00:42:48,414We're doing the body,
    00:42:49,778the arms, the elbows, the forearms and the hands
    00:42:52,394all in one go.
    00:42:55,041And a lot of times, you would separate that out.
    00:42:57,262If this character's wearing gloves, for example,
    00:43:00,204then it makes no sense to try and do this all in one piece.
    00:43:03,027But, for the purposes of this tutorial,
    00:43:04,848I'm gonna show you how to do it in one go.
    00:43:06,940So, I just put a seam down the back of this character, here.
    00:43:12,062And I'm gonna extend the seam up a couple more polygons,
    00:43:15,614just in case.
    00:43:18,155And now, what I'm gonna need to do
    00:43:20,813is figure out where to cut for these hands.
    00:43:25,587Now, I wanna be able,
    00:43:28,687the most visible part of this alien
    00:43:31,037is gonna be the top of the hands.
    00:43:33,114The bottom won't be as visible.
    00:43:35,896So, I'm gonna try to create a seam
    00:43:40,064where I'll basically have the top of the hand,
    00:43:43,277and then it will be mirrored by the bottom of the hand,
    00:43:47,819and that way the thumb will be sort of
    00:43:50,393linking the top and the bottom of the hands together.
    00:43:54,323So, I need to figure out which seam to cut here.
    00:44:00,681And I think it's whatever seam this is here,
    00:44:03,663cause it's right in the middle of the fingers.
    00:44:05,776So, I have the back selected,
    00:44:09,005that back edge,
    00:44:10,016I'm gonna hold shift,
    00:44:11,150and I'm gonna start drawing this seam here.
    00:44:14,416And I'm just gonna follow it
    00:44:17,488all the way
    00:44:22,177back to this seam.
    00:44:24,313Alright, now I'm gonna come back here.
    00:44:26,218And I need the seam to go all the way down the hand,
    00:44:32,053through all the fingers,
    00:44:36,456and this is one of the reasons the Path Selection Tool
    00:44:39,255is so great,
    00:44:40,335it'd be really hard to use the Direct Selection Tool
    00:44:45,042and get these little bitty
    00:44:46,851edges that are kinda hidden in there.
    00:44:49,224When you use the Path Selection Tool,
    00:44:52,507you can just kinda draw the direction,
    00:44:55,569and it will figure it out for you.
    00:44:56,978Alright, so now here,
    00:44:58,547I need to kinda decide where my seam's gonna be,
    00:45:01,275and I'm gonna try to hide it in the crook of the hand, here.
    00:45:06,393It comes down the thumb,
    00:45:09,430comes up this side of the thumb and then that side's done.
    00:45:12,428Alright, so that's the seam for one side.
    00:45:14,993So, now we have to do the same thing
    00:45:18,688on this side.
    00:45:37,896And this is very tedious,
    00:45:39,466and there's really no way around it, unfortunately.
    00:45:46,289A lot of,
    00:45:48,009a lot of things you have to do
    00:45:50,725in involved characters.
    00:45:53,833They're very tedious.
    00:45:55,124It's just the nature of it.
    00:45:56,849If you wanna work at Pixar,
    00:45:58,689you're gonna do this a lot. (laughs)
    00:46:01,100Alright, so here,
    00:46:02,116we have the same issue,
    00:46:03,657we need to go down and hide it,
    00:46:06,198kinda in the crook of the hand, here.
    00:46:08,828Come around the thumb,
    00:46:10,767up the side of it,
    00:46:12,396and one last edge, and we're good.
    00:46:17,882So, we have a nice edge to cut, in theory.
    00:46:21,463We'll see what happens.
    00:46:24,404So, now we're gonna go back into a UV edit mode,
    00:46:27,693and we're gonna go to the Relax UV tab,
    00:46:30,761Cut Selected Edges is checked,
    00:46:32,596Pin Border Points is not.
    00:46:34,092I'm gonna hit apply,
    00:46:35,182cross our fingers,
    00:46:37,638and here we go.
    00:46:39,375This is actually a good result.
    00:46:41,154I'm gonna scale this down really fast,
    00:46:46,968and make sure that I fit it inside the UV area.
    00:46:53,160Now, one thing you gotta keep in mind,
    00:46:54,560when you're UV mapping,
    00:46:55,809you wanna maximize the amount of area you're using,
    00:46:59,804because you have basically 2000 odd pixels,
    00:47:05,046by 2000 odd pixels, here.
    00:47:06,763And the only part of the texture that's actually
    00:47:11,394gonna be put on your image
    00:47:13,027is the part that falls on top of these UVs.
    00:47:15,578So, this big area here, this big area here,
    00:47:18,884this just gets wasted.
    00:47:20,428So, it's basically free
    00:47:21,953texture information resolution you could have
    00:47:25,333that you're not using.
    00:47:26,790So, you know,
    00:47:28,428that's one of the reasons that
    00:47:30,581unwrapping the whole body like this,
    00:47:32,952isn't usually the way you'd go,
    00:47:34,344because you can see it creates this very
    00:47:36,077funky shaped object here,
    00:47:38,769and now I don't have a great--
    00:47:40,753I don't have anything to put in the middle here,
    00:47:42,798so that's just gonna kinda get wasted.
    00:47:44,797I could rotate this, maybe,
    00:47:47,155but then it's gonna make it trickier to paint,
    00:47:49,377so I don't wanna do that.
    00:47:51,958So, for the purposes of this tutorial,
    00:47:53,615this is what we're gonna stick with.
    00:47:54,994Just know that it's best if you can separate things out,
    00:47:58,110and that way you can really fill the space with UVs
    00:48:01,188and get as much texture information as possible.
    00:48:04,244In any case, I am going to select the face here,
    00:48:07,888the face polygons,
    00:48:10,209deselect these,
    00:48:11,458and I'm gonna scale that up a little bit.
    00:48:15,246So we can get a little bit more inside it.
    00:48:19,308Alright, so now, I'm gonna make a new texture layer,
    00:48:23,129and I'm gonna make guides for the body now.
    00:48:27,293So, I'm gonna turn the HyperNURBS on,
    00:48:29,993and with my red color here.
    00:48:35,683So, these are the UV maps for
    00:48:38,456the hands that we just unwrapped.
    00:48:40,498And you can--
    00:48:41,389you'll know because of the way we cut it,
    00:48:43,423that the thumb is here,
    00:48:45,798and then the rest of the fingers are here,
    00:48:47,646but I don't know which side's top and bottom.
    00:48:50,124So, what I'm gonna do is,
    00:48:51,351I'm gonna come over here,
    00:48:52,651and I'm just gonna paint fingernails
    00:48:55,309on the tip of each finger.
    00:48:56,887And now I can see clearly where everything is.
    00:49:00,154And then I'll do the same on the thumb.
    00:49:03,725Alright, so now you know
    00:49:05,816where all the fingers are.
    00:49:09,607Then I'm gonna put a mark where the wrist is.
    00:49:16,376And so, I'm basically just doing the same thing I did
    00:49:19,099with the head.
    00:49:19,932You know, I can make a line where the elbow is.
    00:49:22,356So now I know that's the elbow.
    00:49:25,158And then here's sort of,
    00:49:27,383if this is was a short sleeved t-shirt,
    00:49:29,030that might be where the sleeve is.
    00:49:31,450So I'm just kinda giving myself some guides.
    00:49:33,289Now, in this unused area here,
    00:49:35,085you could even leave yourself little notes.
    00:49:37,736You know, wrist,
    00:49:41,543So, if you were preparing this for someone else,
    00:49:45,209you could hand this off to them, and make their
    00:49:47,176lives easier and they might buy you a beer later.
    00:49:49,725Or, it'll just make your life easier if you're
    00:49:52,784doing a whole bunch of UV unwrapping.
    00:49:56,665So, yeah.
    00:49:58,506So, now this guy is basically ready to go,
    00:50:00,975you could kick this out,
    00:50:02,242go into Photoshop,
    00:50:04,637and start putting a face on it.
    00:50:07,309And just to make sure this works,
    00:50:10,617I'm gonna do a quick test.
    00:50:12,219So, what I'm gonna do is
    00:50:14,249go into Object Mode,
    00:50:16,847and I'm going to Create a UV Mesh Layer,
    00:50:23,773I'm gonna name these a little better.
    00:50:25,314So I have my UV mesh layer,
    00:50:26,848this is my body guide.
    00:50:30,087And I have already gotten rid of my face guide,
    00:50:34,073so I'm gonna quickly just paint
    00:50:38,272the face guide one more time.
    00:50:47,219So my nose was there,
    00:50:53,847hair was somewhere like that.
    00:50:58,242So now I'm gonna save this as a Photoshop.
    00:51:05,077Alright, so we'll call this alien head,
    00:51:12,516go into Photoshop,
    00:51:14,640open up that file.
    00:51:18,181Turn on our UV mesh layer so we can see.
    00:51:20,300We've got our guides here.
    00:51:23,739And now, I'm gonna bring in a picture
    00:51:27,070of my daughter Emmaline,
    00:51:29,244because I happened to catch her facing the camera,
    00:51:32,520which is not easy,
    00:51:33,663if you have kids, you know that that's--
    00:51:35,934that's rare.
    00:51:37,221And I'm gonna paste that photo here.
    00:51:39,087I'm gonna try my best,
    00:51:40,543I don't know how well it's gonna work.
    00:51:42,260I'm gonna try my best to line it up
    00:51:44,531to the face.
    00:51:46,304So, I am going to put it under the UV mesh layer.
    00:51:49,285I'm gonna turn the--
    00:51:50,702I'm gonna leave the face guide on for now.
    00:51:55,703And the first thing I wanna do is do a very quick
    00:52:04,586just on her face.
    00:52:16,239Alright, so the eyes of that alien are down here.
    00:52:22,147I'm gonna actually apply this mask so I can
    00:52:24,629use the Transform Tool.
    00:52:26,429So, in Photoshop,
    00:52:29,796you have a great tool.
    00:52:31,187If you hit Command+T,
    00:52:32,577you have your Transform Tools here.
    00:52:34,753If you then Control+Click that,
    00:52:37,494you can use the Warp Tool.
    00:52:38,902And you can actually stretch the image out,
    00:52:44,076and kinda warp it to make it fit
    00:52:47,827almost any shape you want.
    00:52:50,030So, I know that the eyes need to be here.
    00:52:53,772I can kinda reposition those.
    00:52:57,524Right now my face guide is underneath that,
    00:53:01,878let's get that on top, alright.
    00:53:06,174So, let's go back into the Warp Tool.
    00:53:09,081So, I can adjust the nose,
    00:53:10,863adjust this eye a little bit,
    00:53:13,981this eye's right on the money,
    00:53:17,733and then the mouth's in the right spot,
    00:53:19,484so that's pretty good.
    00:53:21,261Let me turn the UV mesh layer off,
    00:53:23,633and turn the face guide off.
    00:53:26,755And just to see what this looks like,
    00:53:28,233I'm gonna save this,
    00:53:29,549go into Cinema and revert the texture.
    00:53:35,355And there we go.
    00:53:36,795Success, I guess.
    00:53:38,448I'm not sure if that is success.
    00:53:40,964But, you can see that we have successfully mapped
    00:53:45,967a face to this.
    00:53:47,381And you know, you have to clean this up.
    00:53:49,680You may want to--
    00:53:51,946You probably wanna add another layer,
    00:53:55,098grab that skin color and kinda start
    00:53:59,001feathering in the skin tones a little bit.
    00:54:02,994So you can start to fill in the skin
    00:54:05,836on the side, here.
    00:54:10,565So, you still have a lot of work to do
    00:54:11,971to really make this texture work,
    00:54:13,370but you can see that it was really easy
    00:54:15,602to line everything up,
    00:54:17,009and get it where we want it.
    00:54:19,553And, you know, if we wanted to make a blue shirt,
    00:54:22,983and white sleeves, and then pink skin,
    00:54:26,114it'd be really easy
    00:54:27,800to put color and images and texture exactly where we want.
    00:54:33,089And then, if we wanted to do things like bump mapping,
    00:54:36,213or displacement maps,
    00:54:37,904you can still use these UVs and do all that,
    00:54:41,436and have total control.
    00:54:43,269So, there you go.
    00:54:44,411I feel like this is a very long tutorial.
    00:54:46,505I hope it wasn't too boring.
