What Do You NEED For Faster Renders in Cinema 4D? - Understanding Rendering
577A viewer of mine ALMOST spent $550 on a GTX 1080 thinking it would speed up his renders- spoiler alert, it doesn't!
So I'm gonna break this video down into 3 parts that will drastically improve or slow down your render time.
1. Hardware (Computer Specs) What you need, what you don't - save some money
2. Technical - Render settings, textures, polygons, all that
3. Workflow - About you and your effeciency
Hardware:
The important specs you need to know are:
CPU : This is the "Central Processing Unit" - It is DIRECTLY responsible for rendering and calculating things in your scene- as well as the general performance of literally everything on your computer
If you're just a hobbiest that doesn't want to spend too much, a high end Intel i5 or a low end i7 might do. If you're a professional like me, you want a high end i7. If you've got loads of money to wad around, you can even consider getting an i9, but that's only if you've got the extra budget.
As mentioned, the CPU is directly responsible for rendering. The better your CPU, the faster your render times.
GPU : The "Graphics Processing Unit" is not as important as you think for rendering. The only thing the GPU controls is the viewport where you're working in as well as OpenGL/OpenCL/CUDA acceleration.
I'll explain everything in a bit but the key caveat here is that I'm refering only to the default Cinema 4D render options like Standard and Physical.
GPU rendering does exist but it doesn't neccesarily mean it's faster. GPU rendering requires external render engines such as Octane or Redshift and are used to generate physically accurate results- the goal of this is to get photorealistic renders- It does NOT GUARANTEE faster render times.
I mentioned OpenGL/OpenCL/CUDA acceleration earlier, what are they? Well you wanna make sure your GPU isn't too bad, I've only used NVIDIA GPU's and I can say for sure you want at least a GPU 1050 or above.
What the GPU acceleration does for you is:
1. Allow you to do hardware renders
2. Enhanced viewport for previews OR EVEN potentially faster renders
3. Greatly assist with editing
RAM : "Random Access Memory" This is the short term memory for your computer, it's useful for calculating more complex computations like fluid simulations and particles faster.
The worst thing you want is to have a CPU that can calculate everything super fast, but then not have enough RAM to actually do all the calculations.
I don't recommend anything less than 16GB but what you really want to aim for is at least 32GB of RAM.
Now to put this all together, I'll let you know the specs of all three computers I have just to give you an idea of what works for me. Everything I have is relatively decent but not supercomputer level.
My Desktop back in my house in Australia is custom built- it has an i7-7700 and a GTX 1060 with 6GB of VRAM, and 32GB of RAM. I got this in 2017 for around $10,000 HKD.
My new laptop that I'm working on right now is a Lenovo Legion Y520. It has an i7-7700, same as my desktop, but a GTX 1050ti as the GPU. It houses 16GB of RAM. I got this a few weeks ago for around $7,500 HKD. Very good bang for buck.
My oldest laptop that isn't my Mac is an Asus notebook that's no longer in production. It has an i7-5500 but only a GTX 940M as a GPU. This one is not capable of GPU acceleration and is a pain to use. It houses only 8GB of RAM. This was bought in 2014 or 2015 for around $8,000. You could probably pick this up for a low low LOW price now but, please don't.
Some of this info will be extremely relavent when it comes to the third part of this series.
