- XPU does not currently support redirection of errors away from the console, which means DCCs will not be able to report XPU errors in their UI.
- Warnings on the console when rendering to XPU from Katana. There are some warnings you will see on the console about a bad DSO being found for the socket display driver. You can ignore these.
- Picking from "it" does not relay the selection back to RenderMan for Maya
- RenderMan for Maya does not yet support batch rendering to XPU
