    Yusarina released this 2026-07-30 11:40:49 +00:00 | 19 commits to main since this release

    This is the biggest CATS update in a long time. It introduces a completely new translation system, adds glTF and GLB importing, brings new UV tools into CATS, significantly reorganises and polishes the interface, improves Rigify handling, and integrates our new wiki throughout the add-on.

    Hopefully there are no bugs. xD

    Our new wiki is now live:

    https://git.neoneko.org/Yusarina/Cats-Blender-Plugin/wiki

    ⚠️ Deprecation Warnings

    Material Combiner and Atlas Generation will be removed in CATS Blender Plugin 5.2.4.0.

    The current external Material Combiner plugin will be replaced by a new built-in CATS material tool.

    Immersive Scaler will be removed in CATS Blender Plugin 5.2.5.0.

    The current external Immersive Scaler plugin will be replaced by a new built-in CATS scaling tool.

    These plugins are no longer maintained by the original authors.

    Deprecation warnings are now shown directly inside the relevant CATS panels.

    Added

    • Added glTF and GLB importing.
    • Added a new pluggable translation system with support for:
      • Google
      • DeepL
      • LibreTranslate
      • MyMemory
      • Internal dictionary only
    • Added a Translation Service dropdown, allowing users to choose their preferred translation provider.
    • Added unit tests for the new translation providers.
    • Added a new UV Tools panel to the UV/Image Editor.
    • Added Align UV Edges to Target, ported from Avatar Toolkit.
    • Added Find Shortest Seam Path with a rewritten breadth-first search system.
    • Added Find Shortest Seam Path to a new collapsed UV Tools panel in the 3D View sidebar.
    • Added a new Bone Tools panel.
    • Added help icons throughout the interface that open the relevant section of the new CATS wiki.
    • Added shared interface helpers for section headers and wiki buttons.
    • Added hint text to sections where the available actions were not immediately clear.
    • Added the missing noShapekeys translation string.

    Changed

    • Replaced the outdated and unmaintained google_trans_new package with a built-in translation provider system.
    • Translation dictionaries are still checked first, with the selected online service only translating missing entries.
    • Translation providers now fail safely when a service is unavailable.
    • Translation service settings are now stored in the global CATS settings file.
    • Relabelled the old Use Old Translations option to better represent the new multi-service translation system.
    • Unified Rigify detection through Common.is_rigify_armature.
    • Removed the duplicate inline Rigify detection block from Fix Model, as the shared validator already handles both conditions.
    • Moved valve_resources from extern_tools into the main resources directory.
    • Reorganised the CATS sidebar and reordered panels into a more logical order.
    • Added Fix Model to Quick Access.
    • Renamed MMD Options to Converters.
    • Moved the Rigify, Valve and VRM converters into the Converters panel.
    • Moved translation tools into a dedicated Translation panel.
    • Renamed Custom Model Creation to Merge & Attach.
    • Renamed the internal Fix Koikatsu Shapekeys functionality, which was incorrectly named as a VRM shapekey fix despite not being intended for VRM models.
    • Updated the Fix Model warning to clarify that it is intended for MMD and VRM models.
    • Reorganised the Optimization panel into:
      • Materials
      • Mesh Cleanup
      • Shape Keys
      • Bones & Weights
      • Atlas Generation
    • Moved Join Meshes and Remove Doubles out of Material Operations and into the relevant mesh sections.
    • Removed the old Mesh Tools panel and moved its tools into the relevant Optimization sections.
    • Moved Atlas Generation to the bottom of the Optimization panel because it is being deprecated.
    • Made all Optimization sub-panels collapsed by default.
    • Added consistent boxed sections throughout:
      • Quick Access
      • Converters
      • Merge & Attach
      • Translation
      • Bone Tools
      • Bone Parenting
      • Visemes
      • Scaling
      • Eye Tracking
      • UV Tools
      • Settings
    • Added spacing below section headers so they no longer sit directly against the first button.
    • Removed trailing colons from section titles that were previously formatted like inline labels.
    • Added titles to sections that previously had no header.
    • Removed unnecessary boxes where the panel name already provided enough context.
    • Split long labels, descriptions and button rows so they fit better inside narrow sidebar panels.
    • Improved the layout and field spacing in the Visemes and Eye Tracking panels.
    • Changed the eye-tracking progress bar so it is only displayed while an operation is running.
    • Removed the old How to Use, MMD Options Wiki, Tutorial, and Support Us buttons.
    • Removed the inline UV tool instructions, as this information is now available on the wiki.
    • Updated the Credits help button to open the new CATS wiki.
    • Translated the remaining hardcoded interface labels.
    • Updated all supported locales to match the redesigned interface.
    • Removed unused bmesh code from the UV edge alignment tool.
    • Narrowed exception handling in the new UV tools to expected error types.

    Fixed

    • Fixed the faulty UV repair report in Fix Model never appearing.
      • The repaired UV counter is now preserved across all processed meshes instead of being reset before the report could read it.
    • Fixed MMD bone-morph baking producing empty shape keys on Linux.
      • Bone morphs are now baked from evaluated mesh positions instead of the undeformed base mesh.
      • Bone posing now uses matrix_basis, allowing Euler-mode bones to bake correctly.
      • Temporary modifiers, shape-key state and bone poses are restored after baking.
    • Fixed the previous Find Shortest Seam Path search being unreliable by replacing it with a cleaner breadth-first search implementation.
    • Fixed Find Shortest Seam Path unnecessarily requiring an armature.
    • Fixed long labels, descriptions and button rows being truncated in narrow sidebar panels.
    • Fixed the eye-tracking progress bar appearing when no eye-tracking operation was running.
    • Fixed translation failures potentially interrupting the translation process when an online provider is unavailable.
