Functions

• BakeMaps: fixed an issue that generated incorrect results during the baking of AO texture maps (ComputeAO).
• IdentifyPatches: fixed an issue that could cause crashing.

• Selection by maximum size: fixed an issue that could cause crashing when users search for small objects, then create occurrences from the selected results.
• Object IDs: fixed an issue that caused the same ID to be generated for two cubes after their creation in a scene.
• Resizing UVs to texture size: fixed an issue that caused crashing.
• Deletion of occurrences:

Security

The security vulnerability is now fixed.

Known issues

• If you launch Pixyz Studio for display on a secondary monitor, the Viewer appears white and the scene is not displayed. This issue is caused by a conflict between nVidia GPUs and another software. Check this page for a work-around.
• Animations that are exported to USD formats (.usda, .usdc, and .usdz files) may not behave properly.
