🔨 Updated OpenUSD to version 26.08

August 28, 2026​

✨ Initial support for importing OpenPBR materials via USD
✨ New feature to apply transformations from nodes to meshes where possible

July 31, 2026​

⚡ Fixed a rare crash bug resulting from not properly catching malformed GLTF inputs

June 29, 2026​

🔨 Added support for boundary preservation factor fixing boundaries during decimation so they do not get decimated at all

⚡ USD exports now always specify an up axis explicitly
⚡ USD exports now define the node under which materials are defined as type Scope instead of undefined

May 27, 2026​

🔨 USD export can now export tris and quads if there are per triangle materials
🔨 Triangle to quad conversion should now be more robust against duplicated vertex data
🔨 Splitting by material more consistently ensures that there are no multiple materials on a mesh

⚡ Fixed Cylinder UV unwrap scale setting not working properly
⚡ Fixed possible incorrect scaling of charts when unwrapping multi-material meshes
⚡ Fixed atlasFactor being ignored in some cases

April 24, 2026​

🔨 Conversion of multiple UV atlases to UDIM layouts should now be possible for multiple meshes without first flattening them into one

April 23, 2026​

🔨 Winding order repair with a decision per lump will now remove duplicate vertices first
🔨 More robust conversion of multiple UV atlases to UDIM layouts

April 20, 2026​

✨ Experimental feature to convert multiple generated UV atlases into a UDIM layout
✨ Experimental feature to store metadata extracted from CAD files in USD (disabled by default)

🔨 Filling of circular surface holes now takes node scaling into account
🔨 UV packing is now more robust against degenerate UV triangles
🔨 Removing of triangles with non-finite coordinates is now more consistent
🔨 USD import was made more robust against malformed inputs
🔨 Loading images was made more robust against malformed inputs
🔨 USD export will not produce empty UV primvar indices anymore and set vertex interpolation in these cases
🔨 Display color conversion to material values will now only take effect if there are no basecolor or diffuse values or textures in input

⚡ Fixed normal issues with solid hole defeaturing
⚡ Fixed issues in triangle to quad conversion

🔨 Cube unwrapping UV charts are now packed with regard of respective 3D orientation
🔨 Cube unwrapping UV charts now have a consistent 3d mesh space to UV space mapping to U
🔨 OpenUSD export for assets with an unused UV set now export it if circumstances allow
🔨 Added support for rigid animation import from USD files
🔨 Occlusion culling per lump decision now also covers instanced meshes
🔨 Winding order repair does not force recomputing normals for the whole asset anymore
🔨 Added an optional system setting to restrict allowed inputs to specific file format extensions

⚡ Fixed an issue in removing triangles from meshes with quads
⚡ Fixed a rare crash condition during UV packing
