General


 In General category you can set the following options:




VRay CUDA GPU Device Select


You may not want to use all available GPU devices for rendering, especially if you have multiple GPUs and you want to leave one of them free for working on the user interface or you may want to combine your CPU and GPU together. Enable the desired render device by ticking the checkbox.

We recommend in situations when the video memory of the graphics card is insufficient to use only the CPU as a rendering device. This way you will use the system RAM instead of the VRAM of the graphics card.

You can also set CPU/GPU devices available for rendering outside of Unreal using the vray_gpu_device_select tool located in"C:\Program Files\Chaos Group\V-Ray\Unreal\tools\vray_gpu_device_select.exe" or you can use the shortcut from ІІStart MenuІІ>Programs>V-Ray for Unreal. This tool is useful when setting up CPU/GPU devices on render servers for distributed rendering.
