    Changelog:

    Fixes

    • Fixed an issue where Armature Merging could cause Blender to crash.
    • Fixed a performance issue that made Armature operations extremely slow.
    • Added a potential fix for PMX model texture import issues. (I suspect this is actually an MMD Tools problem all my tests in both Cats and the standalone version gave inconsistent results. Since there’s no meaningful difference between MMD Tools and our version aside from the 5.0 updates, this behaviour shouldn’t be happening. I’m currently waiting for the user who reported the issue to get back to me. This also happens on 4.5, 4.4 and etc so i know it's not the 5.0 changes i made.)

    It is now also recomneded you use our Material Combiner: https://github.com/teamneoneko/material-combiner-addon and Imersive Scaler forks: https://github.com/teamneoneko/immersive_scaler

    This version requires Blender 5.0+ and is not backward compatible with 4.x

    Cats for 5.0 is still in beta, but this update puts a big focus on UI cleanup, stability, and making everything run smoother in Blender 5.0. Please report any issues you find, and let me know what you think of the new UI.
    This build is basically a release candidate for the first stable Cats 5.0 release. As long as no major issues pop up, this will become the stable version.

    Changelog:
    UI Improvements:

    • Cleaner, modern UI for Blender 5.0
    • Less clutter with fewer nested menus (Note, we removed the tabs in favour for sub menus, we did this because labels were cut off on the tab buttons, which caused issues for new users).
    • Quick Access now uses clearer sections
    • More consistent button and panel layout across the addon
    • Improved error and warning visuals to make issues easier to understand
    • Removed outdated or redundant UI elements (like the old FBX test import button)

    Eye Tracking Fixes:

    • Fixed crashes when the required mesh or armature was missing
    • More stable setup with clearer warnings

    General Fixes & Stability:

    • Updated MMD Tools to version 4.5.2, fixing several issues with MMD workflows (Note we still had to upgrade it to work with 5.0, so there maybe some issues still)
    • Fixed Blender 4.5+ crash caused by bone collections being removed in Edit Mode
    • Fix Model no longer crashes on MMD models
    • Addon checks now use short-term caching for better performance
    • Updater now correctly supports Blender 5.0

    Armature & Transform Fixes:

    • Armature merging now respects the Apply Transforms option
    • Fixed unexpected size changes during armature merge
    • Clearer, more helpful error messages when transforms fail

    Overall Addon Cleanup:

    • Cleaner operator descriptions and improved menu organization
    • Removed old debug prints and unused features
    • Reduced duplicated logic across tools
    • More protective error boundaries to prevent UI-related crashes

    This version requires Blender 5.0+ and is not backward compatible with 4.x

    This version brings some changes from Avatar Toolkit, plus memory leak fixes and more.

    Fixes to MMD Model Handling

    • Removed BatchVertexGroupOperations: Eliminates file handle leaks by switching to the stable, individual processing methods. This also removes the need for the previous Linux workaround.
    • Proper resource cleanup: Ensures all resources are released at the end of the fix process, preventing potential crashes on Windows and Linux.
    • Early validation checks: Detects issues upfront to avoid wasted processing time.
    • Lightweight bone name caching: Significantly improves performance across the entire process.

    Armature Merging & Mesh Attachment Improvements

    • Optimized NumPy operations for better performance.
    • Improved vertex group processing efficiency.
    • Consolidated transform validation logic for cleaner, more reliable execution.
    • Removed duplicated code, reducing complexity.

    This should make Cats for Blender 4.5 a bit faster and much more stable, please report any issues.

    Fixes:

    • Fixed an issue on Linux (mainly Wayland sessions) that caused a memory leak when using Fix MMD Model and could crash Blender.

    Note: We had to stop using MMD Tools and switch to a native morph conversion method. This may not be as polished, so please give us feedback if you’re on Linux. This change does not affect Windows, which still uses the original method.
