VRay 3.0 SP1
cecofuli:
Hi
what do you think?
(*) Speed up with opacity map is simply amazing! (O__O)
(*) Random shader very useful!
(*) I miss very much the nice VRay Hair support.
(*) VRay VFB so cool.
Juraj:
The framebuffer is simply fantastic.
Ok, that's some very impressive update overall.
cecofuli:
what impressed me is the speed up with Ppacity map!
Normal = 50 sec
Stochastic = 33 sec
Clip = 26 sec
It's simple amazing. How is it possible!
I remember my old day, fighting with million trees and the "stupid" opacity map!!!
Juraj:
I don't know, I haven't had issues with speed with simple cutout maps (leaves) since I did the whole "none" filtering, although it occasionally get stuck when used in more complicated opacity maps for furniture for example.
I am bit wary of new methods since their whole Embree and Probabilistic failure. Embree is unusuable since it disables (without any threshold) every instance, what do I have, 256GB of ram ? It's usable for those who render boxes.
Probabilistic shaves off time...creates visually wrong look (like most of the time completely different intensity), and introduces new noise.
But these new features do look great. Should have come faster, one year for service pack is bit too long.

Trees are the worst possible scenario of what can happen with opacity maps. It is much easier to find some reserves there, than in clay rendering ;)
