V-Ray Bitmap issue in VRay GPU

[t_h1]

Seems like VRay GPU in VRay6 doesn support VRay Bitmap?

In what way? It works fine with me.

Sorry for less information.
the scene that can be rendered without problems on the CPU wont render bump information in VRay GPU.
Materials are brought from Chaos Cosmos.
Should I change something transition from CPU to GPU?
left one is CPU,right one is GPU
I'll upload the project file

There was a recent report of the bump in GPU needing very big numbers to show up.
In fact, in your scene if you set the vraycolor2bump map height to 1000000 (1 million, up from 0.3934), it will show up.

Thanks for getting us the report, and a way to reproduce it.

Thanks for the scene t_h1

It seems to be an issue with V-Ray Plane and Bump mapping in V-Ray GPU, We will look into that

Lele beats me to it again, we have a fix ready for the bump multiplier on GPU. I will test your scene with it as well

Any plane (even a standard mesh one), indeed it works fine on a sphere.

seems not fixed in beta 2?

seems not fixed in beta 2?

We didn't get the fix in time, it is Work In Progress now
