Can it support mulit-gpu on vray for rhino 2?

and Can I choose what gpu card to do rendering?

Yes, multi GPUs are supported.

You should have ocldeviceselect executable as part of V-Ray installation. With ocldeviceselect you can set what GPUs you want to use for rendering (in fact it just sets env variable named VRAY_OPENCL_PLATFORMS_x64 with values something like {NVIDIA CUDA, GPU,1,0} - this will disable the second GPU if there is any and will use just the first one).

You have to restart V-Ray in order these changes to have any effect.

thank you for reply!


if I have a 4 display card, how can I set to disable to use the first card, and use others?

Thank you very much!

It seems that this executable is not part of the installation, sorry for that.
Please, tell what operating system are you using and I will upload it for you.
After that you just have to start it, choose what GPUs you want to use from a window and restart V-Ray.

My system is Windows 7 64bit, thank you very very much!

You got PM, I will talk with the guys from V-Ray for Rhino to add the file in the installation.
Sorry for that again.
Best,
