Release Notes

• New features and improvements:

  • Significant performance improvements across all MeshOptimizer features

  • Native support for Apple ARM

  • Various improvements to welding algorithms

  • Intermediate images are no longer written to disk

  • Runtime dependencies such as pngquant and pngcrush have been removed

  • Intersections

    • Enabled intersection removal between transparent and opaque polygons

    • Ignore intersections between transparent polygons both in intersection removal and editing requests

  • Material cleanup

    • Remove geometry for invisible UV islands

    • Rasterization based cleanup for single color material textures

• CLI changes

  • Added proper support for embedded glTF on output via the --embedded_gltf flag

  • Added --preserve_empty_nodes flag which doesn’t delete leaf nodes that don’t contain any scene objects

• Bug fixes:

  • Fixed a bug where skin was left on a node that lost its mesh (e.g. due to mesh being removed)

  • Fixed a bug with degenerate polygon removal on mesh boundaries

  • Fixed a crash in atlassing when textures are larger than maximum atlas size

  • Fix a crash that could occur when empty meshes weren’t cleaned up

  • Fixed a bug where images used with both blend and mask alpha modes could be alpha boosted

  • Fixed incorrect amount of ECT1S KTX compression being used for RGBA images

  • Cameras are now correctly handled when --freeze_tranform flag is set

  • Fixed transparency propagation through edge collapse

  • Fixed --force_one_uv_layer flag which was in some cases removing remove UV layer 1
