- XPU currently only outputs EXR or TIFF frames.
- Adaptive sampling is yet to be implemented.
- Only some geometric built-in AOVs are available under the same name as they are available for RIS.
- The motionFore and motionBack AOVs are not currently supported in 25.0. This means that the denoiser will not be able to take full advantage of cross-frame denoising for XPU rendered images. This will be addressed in the 25.1 release.
- Multi-camera, multi-frame is not yet supported.
- The "weighted" option for the pixelfiltermode parameter to the Hider will not be supported.
- Baking - either at the pattern level via PxrBakeTexture or at the renderer level to bake global illumination is not yet supported.
- Cached presence or opacity is not supported in XPU. XPU renders of transparent surfaces may be sharper as a result (they will not be biased by the micropolygon size).
