What is Arnold Render and Why You Should Use it.
While there are a lot of rendering options out there in Cinema 4D there are four main third-party render engines you need to know Arnold, Octane, Redshift and Cycles. We thought it'd be fun to take an in-depth look at all four of these amazing tools and discuss why you might prefer one over the other for rendering in Cinema 4D.
In this article we will introduce you to Solid Angle’s Arnold Render Engine. This post should be a good overview if you've never heard of Arnold or if you're curious about using it in Cinema 4D.
Some of the terms used in this article series may be a bit geeky to say the least. If you find yourself wondering what any of the terms mean, check out our 3D Glossary.
What is Arnold Render?
As written on Solid Angle’s site, “Arnold is an advanced Monte Carlo ray tracing renderer built for the demands of feature-length animation and visual effects.”
Broken down, Arnold is an unbiased CPU render engine that uses a technique, Monte Carlo, for rendering. We told you this would get geeky...
That means Arnold prides itself on obtaining photorealistic renders far above what you can get out of the standard and physical renders in Cinema4D. That leads nicely into why you may consider using Arnold in the future.
Why should I use Arnold Render?
The job of these first few articles isn’t a compare and contrast. We’ll follow up with one of those shortly. This is just the facts so you can make an informed decision in your career.
#1: SOLID IS IN SOLID ANGLE’S NAME FOR A REASON
Arnold is extremely solid. You can throw gigantic scene files at it and with a great degree of certitude knowing you won't have to worry about Arnold crashing and being unable to handle the scene. Why else would it be used so heavily in VFX and movies?
#2: ARNOLD LOOKS BEAUTIFUL
Arnold has a quality about it that can make images look as close as you can get to photorealistic. Part of that is because Arnold is an unbiased render engine. That means it tries to mimic the real world as closely as possible without taking short cuts. It also has to do with the algorithms it uses behind the scenes to calculate its images.
#3: INCREASE YOUR WORKFLOW SPEED WITH THE IPR (INTERACTIVE PREVIEW REGION)
This isn’t something only Arnold can do, however it is a big perk of using any 3rd party render software. An interactive preview region is a window that shows you what your rendered scene looks like in almost real time. No more hitting Ctrl/Cmd-R and waiting 10 minutes to see if your scene looks okay with that new lighting setup. When you update your scene, the IPR updates almost instantly, increasing your workflow exponentially.
#4: USE ARNOLD ANYWHERE
Arnold is just about everywhere. If Cinema4D isn’t the only 3D application you are using, it is likely Solid Angle has put out a plugin for whatever else you’re using. Currently, Arnold has plugins for Cinema4D, Maya, 3DSMax, Houdini, Katana, and Softimage. Solid Angle doesn’t charge you to use additional plugins either. You can easily hop between 3D applications without needing to spend any more money.
#5: ARNOLD’S WORKFLOW TRANSLATES WELLS TO OTHER ENGINES
Learning Arnold is a great way to build a foundation that carries over to other render engines. Arnold’s shader and material system uses common terminology, and a node based workflow, that can be found in other render engines. If you are on a team that uses Arnold, and move to another shop that uses Redshift, you’re going to notice a lot of similarities. It is kind of like learning to drive in a Toyota, and then driving a Ford. There are differences, but it is all basically the same, too.
#6: ARNOLD IS CPU BASED
PAUSE: Now before you run off and shoot us emails about how CPU is so slow and everything is going GPU...cats and dogs living together, I am Zuul…take a breath and read this.Arnold being a CPU third party render engine means that it works on both PC and Mac. You can download it right now on whatever workstation you're using. If you’re a hardcore Mac user, this is a really big deal. I read so many threads about Mac users switching to PC so they can upgrade to using GPU based render engines. You don’t necessarily have to upgrade your hardware to take advantage of Arnold. How ‘bout dem apples? Being CPU also means it has one big advantage over GPU...
#7: THERE IS A TON OF RENDER FARM SUPPORT
Since Arnold has been around since the late ‘90s, it has a large following. That means you can very easily find a render farm that supports Arnold. If you’ve got a really big job and your scene is taking 15-minutes a frame to churn out, send it out to a place like PixelPlow and get it back the same day.While there are a couple render farms that support GPU render engines, it isn’t like CPU and Arnold support.
Reasons Not to Use Arnold?
As with any third party render engine, it is something else to buy. Cinema 4D and other 3D applications cost quite a bit of money. Adding something else on top of that isn’t always something feasible or desirable. Especially as a freelancer.
It is one more thing to learn. It isn’t a one-to-one correlation to the standard and physical materials in C4D. If you’re a beginner or still not accustomed to what Cinema 4D is able to do out of the box, you probably aren’t ready to move on to a third-party engine.
Lastly, at the time of writing, Arnold is a CPU engine when everything is moving towards using GPUs. While we did say this is a perk, it is also a hindrance. It isn't going to be as fast rendering locally and you will need to take advantage of render farms. It really is a catch-22 situation at the moment, so be sure to check back in the future as the world of rendering evolves.
