V-Ray next minor stuff

[Lapaev]

The ipr is crazy fast and gpu support is really nice.

Couple things for GPU part:

1) I have been asking for Dispersion support on GPU for years now It seems like a quite a vital "Visual" feature, why no interest in implementing it?
2) Can you guys add support for Projection node when it's plugged into Layered texture, it supports regular place2d only right now. Attached screenshot right before it crashed In CPU it shows up as checker in gpu it's just solid color.

Dispersion is on the "to do" list and we'll get to it. Surprisingly it's not really a vital feature. I agree that it's nice to have and we'll do it, but even the standard V-Ray managed totally fine without dispersion for a long time. It can also be approximated with three refractive materials inside a VRayBlendMtl material.

Best regards,
Vlado

The GPU currently only supports camera and planar projections. If you're using any other type for the projection node, it won't work. The VRayTriplanar texture works, though, so you can try it instead. Actually, what's the projection type that you're using in this setup, I can't really tell by the screenshot.
