The color spaces Raw and srgb_tx are used in the .mtlx files, but are not part of the list of supported MaterialX color spaces: https://github.com/AcademySoftwareFoundation/MaterialX/blob/main/documents/Specification/MaterialX.Specification.md#color-spaces-and-color-management-systems

It should be straightforward to rename them

  • Raw -> lin_rec709
  • srgb_tx -> srgb_texture
