Faces are flipped in exported glTF file when exporting Marbles sample scene

Omniverse Apps USD Composer (Create)
1

To reproduce:

  • open the Marbles sample scene
  • export as .glb file

Ends up as ~1GB file, seems the textures are broken (see my other post), but this is a separate issue: some objects end up with inverted normals.

I checked some of the settings inside CREATE, but seems there the objects are correct. From a quick comparison it looks like everything set to “Orientation: rightHanded” exports correctly and everything set to “Orientation: leftHanded” exports with flipped normals, which sounds like a bug. But even after switching the “leftHanded” objects to “rightHanded” they export incorrectly.

Looks like face directions are also flipped when exporting to FBX.
