Support KHR_materials_unlit #17

Closed pablode closed 1 month ago

pablode commented 2 years ago

Extension spec: https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Khronos/KHR_materials_unlit

The extension can not be correctly represented with a UsdPreviewSurface, but we might be able to emulate it using the emissive color.

In MaterialX, this feature should be covered by the recently introduced 'unlit' shader node: https://github.com/AcademySoftwareFoundation/MaterialX/pull/860
