Omniverse and UsdPreviewSurface for portable materials

Last video I hacked an NVIDIA Omniverse material to add in my own texture file. This little video shows using the more portable UsdPreviewSurface material to load up your own texture (PNG etc) file. There is also a trick in Omniverse where it will use Omniverse more advanced materials if available, falling back to the less powerful but more portable UsdPreviewSurface in other systems.
