Im still having quite abit of trouble getting RT for GPU to be usable or reliable. I was under the impression that most stuff where fixed when rendering on the GPU now (and the main issue is to fit everything on the GPU memory rather than not rendering properly).
However, we got a scene where we can test a bunch of vray-related stuff for example checking if a new vray version renders predictably in our pipeline, or to benchmark/troubleshoot computers.
It renders just fine on RT CPU, but when swapping to GPU quite a lot starting to look wierd.
This is tested on vray version is 3.10.01 official build, and Maya 2015 (2016 renders the same errors however). And on a Quadro K5200. I havnt tried the latest nightly yet, but I cant see any direct changes in the release notes that would affect this.
I sort of understand why the floor renders strange, as that shader is built with a singleSwitch node that randomizes some wood textures. I assume singleSwitch does not work on the GPU yet?
However the skin shader, normal fog color, 2d displacement, translucency with fog color, 2 sided mtl, hair shader and textures rendered manipulated with a ramp through a rgbToHsv all seems to render incorrectly.
Im surprised the substance file renders just fine, tho.
Here is an image sort of explaning what the different stuff is (it was not made for this purpose so it might be abit brief).
If you need to take a look at the scene you can download it here:

And just remove the xGen fur for quicker testing Takes abit of time compiling the geometry.
Thanks in advance,
Simon
