Release Notes#

Warning

The USD ecosystem is becoming more strict in enforcing standards. In some cases this can break older assets authored previous to these changes. We have introduced an Asset Validator Extension to help fix these issues and create more robust assets. If you suspect something is wrong when you load an asset or you see a warning, please run the Asset Validator extension which can be found under Windows > Utilities > Asset Validator. Refer to the Asset Validator documentation for more info or to the materials related documentation about the Asset Validator.

Kit 110.0#

Release Date: Mar 2026

Added#

Introduced OpenPBR Surface as a new material template.

Improved#

This update prioritizes stability and bug fixes.
OpenPBR Surface in Omniverse handles geometry_thin_walled as uniform boolean parameter, which is consistent with the OpenPBR specification but not yet reflected in MaterialX reference implementation.

Known Limitations#

Sheen and thin film effects are not yet supported by the RTX – Real-Time 2.0 mode. This includes sheen in OpenPBR Surface.

Known Issues#

MDL based workflows like Distill and Bake or MDL Export are not yet compatible with the optional, and by default deactivated, material merging in the Scene Delegate.
