Doing some material tests, so I created this weird widget for testing them... he's friendly honest, Introducing friendly material test widget guy:
Faking Color Dispersion, this is done by rendering it 3 times with slightly different IOR value. Then puting each render into R, G and B channels in photoshop.
1st = one pass, 2nd = 3 passes joined, 3rd = Post Effects
In future vray versions for C4D you should be able to do this effect in 1 render using Blend materials... which would be nice as this naturally takes 3x longer to render! and is a fiddle
The GI is quite low and is only using GI caustics so It's quite blurry.

($16 million for the above, my render cost considerably less)
And here a bigger render:
And in green:
The fancy bloom/drity lens effect is done in post by Maxwell's Simulens, render done by Vray
Working on re-rendering some old engineering visualizations:
Struggled to clean up the CAD model for the above cog. It's much better but It's still got glitches in it. Render took 30 Minutes at 1920x1200 with brute force.
And some Post Work for a different look:
Polished an old piece, still needs more to it, but this will do for now.
And before:
This is what I'm working on right now, Still lots to do, trying to get SSS to behave:
