USD Preview Surface Rendering

[Measter]

While the docs say it's supported, I can't appear to render USDPreviewSurface in the VRAY Renderer. When I render the mesh is black. There are lights in the scene, I've tried Vray and Maya standard lights. Is anyone else having this issue?

Seems to work fine on my end. Could you attach (or send) a simple scene along with the .USD file so we can take a look?

So I ran some more tests and found that USDPreviewSurface only works when the data is imported/referenced as USD data on a USD layer. If you make a cube in Maya and assign a USDPreviewSurface it doesn't work (renders black), and if you export that same cube and import it (not to a USD stage/layer) then it still won't render. Is this the expected behavior? I would love to be able to render USDPreveiwSurface on Maya geometry.

Yes, you are right. It'll be implemented soon enough.
