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
