A number of artists have successfully created plasticine and putty like materials before - though this one stands out more than most due to its humour and great animation....done in Maya i believe.
I was stunned to read that they had spent 6 hours a frame rendering with Maxwell Render 1.7.
Some things take longer than others to render obviously, but for some red blobs in a studio lighting environment, this is clearly the wrong approach and the wrong renderer for the project.
Sure, it looks pretty - but if i told my boss....or even fellow workers that it was gonna be 6 hours until we could see a clean crisp render....well, i dont think i would have a job anymore. I would love to have 6 hours to spend on a frame.
Maxwell is of course an unbiased renderer - meaning its a hands down, brute force physically correct render - respecting the exact information you give it from real world values.
This is great, amazing and gets beautiful results - but im amazed the guys at MeindBender could spare this amount of time to generating the imagery.
As an example and comparison as to this crazy decision to use Maxwell - i created a plasticine material with the Brazil RS inside of 3DSmax. Brazil is an amazingly advanced QMC based renderer - with a powerful balance of quality and speed.
It also comes with its own optimised photometric lights for accurate Kelvin controls etc.
The first render was done in just over two and a half minutes. There are two GI/indirect illumination bounces, two photometric lights with varying temperatures and full, bi-directional sub surface scattering. Oh - and theres also displacement and bump in there, an HDRI reflection map and anti-aliasing/sampling at Min 1 and Max 2.
The second render is exactly the same, except for the sub-surface is turned off. It still looks respectable and we have a considerable time saving. Note the warmth and softness the SSS brings to the first example however - spreading light around inside of the fingerprints and recessed areas.
And ill point out again the render times, as noted on the renders.
Heres a blob with eye balls.
