VRay RT strange result

[enricocerica]

Hi,

I ma a quick test with VRay RT and I get a very strange problem while using OpenCL :

I'm using Nvidia GTX480 & GTX580
Drivers version : 310.70
Cuda (well souldn't be relevant with Open CL) : 5.01
Everything seems ok in the log, the cards are well recognised and there is no particular message

Any idea ?
Thanks

Here is the CPU result (no Open CL)

I have the same problem as you. There are other problems with open cl for me that might also exist for you. When using textures set their blend mode to none and make sure U have UV unwrapped the mesh. Does displacement work for you on OpenCL.

Well, I didn't test anything other then a single rendering as for now it is unusable for me. I asked to Chaos Group support, I hope to get some advice quickly.
