Some USD Prims not rendering correctly

Open stefanminning-autodesk opened this issue 2 years ago • 2 comments

Describe the bug Some USD prims do not render correctly, or at all.

To Reproduce Render the attached USD scene.

Note that all the objects share the same material (Standard Surface with a checkerboard shader) and hence should show up with a similar checkered pattern in the render.

You should instead see that:

  1. The only object that behaves as expected is the sphere: It renders correctly and shows the checkerboard texture.
  2. The plane on the left doesn’t seem to render at all (not from the other side either, so it’s apparently not a single-sided geo problem).
  3. The cube renders, but appears to be missing UV coordinates, so it’s entirely blue instead of checkered.
  4. The capsule renders, but it is missing UV coordinates as well as the end caps, so really it’s more of a cylinder than a capsule.

Expected behavior The rendered objects' shapes should match the appropriate USD prim type and what is shown in the viewport. The checkerboard pattern should appear on all prims.
