- Custom Bxdf or Displacement plugins are unsupported.
- MaterialX Lama support will be implemented in a future release.
- In XPU, we support the following SSS models:
- Burley Normalized
- Exponential Path Traced
- Non-Exponential Path Traced
- subsurfaceSubset is not yet supported.
- Single scattering support in PxrSurface is not complete because volumetric light transport is not fully supported in XPU.
