Hi there,
I just upgraded to vray 3.4 because of the support of max 2017 and I immediately found two issues that I need to get fixed asap...:
We do a lot of medical animations with scenes almost completely consisting of VrayFastSSS materials. Since we have very short turnarounds for these animations most of the time, I found the following combination to work best for me:
I mostly use "prepass based illumination" in the SSS settings and "adaptive subdivision" as my image sampler.
That usually gave me good results with very fast rendertimes.
I can probably live without adaptive subdivisions (the new sampling methods seems to do a good job "out of the box" without a lot of tweaking), but the prepass based illumination now produces ugly colored blotches.
I already tried a couple of things, the only thing that brings down the samplings is lowering the prepass rate, but the lower it gets the less of an SSS effect I seem to get.
Using "raytraced" as my multiple scattering method produces good results, but rendering times are 4-5 times higher (at least with my first tests).
So...can you help me out here? Is there anything I need to do differently to get prepass based illumination to work again...? Or is there a way to speed up the raytraced method (I´m not even using raytraced reflections)?
