v-ray gems

A while ago I tried to render a diamond. This one is done using V-ray for maya. Mental ray does not provide dispersion which can be observed in diamonds. I found out that you can achieve this in post by assembling a few renders with different IOR and colors. This is my first try with vray. I've added zdepth, chromatic aberration and bloom in post. Caustics don't look that natural but because my computer was struggling with this dispersion a lot a don't want to burn it in second try:D.

@Edit:

I'm adding a screenshot of my shader setup f any one is interested.

CAUSTICS - tutorial

Jak mowiłem zanim sie odezwe minie troche czasu no ale coż :P. Chciałbym sie podzielić takim małym tutorialem o efekcie kaustycznym w Mental Ray'u (oczywiscie w 3ds max'ie), który powstał swego czasu. Pokazuje jak uzyskać w miare fajny efekt tak więc zapraszam.

As i said it's gonna take me a while to respond again:P.

I would like to share a small tutorial about Caustics in Mental Ray (3ds max of course;]).

It shows you how to gain an effect as shown above.
