- Add compiled KKBP_Exporter.dll for export functionality
- Binary provides native exporter implementation for the pipeline
- Required dependency for model export operations
- Add new `apply_better_fbx_orientations` operator as standalone UI action for applying bone orientations
- Add "Delete Accessory Bones" property and UI toggle in EXTRAS panel for optional bone cleanup
- Move bone orientation logic from `modify_armature` execute method to new dedicated operator
- Refactor accessory bone deletion into separate method callable from new operator
- Update panel UI to show better FBX bones operator with delete accessory bones toggle option
- Register new operator in `__init__.py` and export from modifyarmature module
- Update interface dictionaries (English, Japanese, Chinese) with new UI strings
- Enable better FBX orientations and accessory deletion only for Koikatsu armature (C) selection
- Add detailed logging for bone operation counts and status tracking
- Add tail position definitions for left and right pupil control bones (cf_J_hitomi_tx_L and cf_J_hitomi_tx_R) with Z-axis offset of 0.01
- Remove IK control bones (cf_pv_*) from must_keep_bones list for C model armature cleanup, as these are not needed in subsequent KKBP steps
- Update must_keep_bones comments to clarify that IK control bones are intentionally excluded during C model processing
- Improve logging message to explicitly indicate that deleted accessory bones include IK control bones
- Add inline comments to pupil control bones in must_keep_bones list for better code documentation
- Add 74 head bone tail position definitions to better_fbx_bone_tails dictionary for improved bone orientation accuracy
- Create backup file modifyarmature_bak.py for version control
- Conditionally apply delete_accessory_bones() only for Koikatsu armature type (C)
- Add cf_J_hitomi_tx_R and cf_J_hitomi_tx_L to preserved bones list
- Implement conditional bone reorientation logic for non-Koikatsu armature types (A/B/D)
- Simplify leg bone tail relocation by removing better_fbx data check and always applying standard z-alignment
- Improve armature modification workflow to handle different armature types with appropriate bone processing strategies
- Add core addon files (__init__.py, KKPanel.py, preferences.py, common.py)
- Add import pipeline with armature, mesh, and material modification modules
- Add export pipeline with material baking and FBX preparation utilities
- Add material combiner tool for texture atlas generation and optimization
- Add extras utilities for animation, rigging, and asset management
- Add bone orientation data from better_fbx for accurate skeletal structure
- Add comprehensive documentation and wiki with multi-language support (EN, JP, ZH)
- Add animation library retargeting lists for ARP and Rokoko motion capture
- Add Rigify integration scripts for advanced rigging workflows
- Add shader file (KK Shader V8.0.blend) for material rendering
- Add manifest and license files for addon distribution
- Add changelog documenting version history and improvements
- Initialize complete Blender addon project for Koikatsu character import/export
