In XPU, the expected workflow for heterogeneous volumes is via aggregate volumes.Textures with a non square pixel aspect ratio are not supported.PxrBakeTexture and PxrBakePointCloud are not supported.PxrDirt & PxrCurvature require the trace() OSL call, which is not yet supported.There is no support for custom C++ plugins.MaterialX Lama support will be implemented in a future release.Custom Bxdf or Displacement plugins are unsupported.RenderMan for Maya supports batch rendering to XPU (PxrPathTracer integrator).Picking from "it" does not relay the selection back to RenderMan for Maya. ![]() There are some warnings you will see on the console about a bad DSO being found for the socket display driver.

If you are running XPU inside of Maya, Houdini, or Blender, this will bring down your application as well. ![]()
