I am using the CC Auto Setup in 3ds max and selecting VRay GPU_7_update 1 when importing the .FBX export from CC 4.
VRayOSLMtl is NOT supported for VRay GPU Rendering.
VRayOSLMtl is being used in in the Normal Map slot.
As a result...when rendering using GPU...Normal maps are not ON.
Please fix this...and look to see what Materials are supported for GPU.

This also applies to VRay Vantage as well.



thanks,
Ed
