Pawlygon Unity Tools\n\nUnity Editor tools for Pawlygon's avatar face-tracking workflow.\n\nThis package helps you duplicate source avatar assets, prepare a working folder structure, swap updated meshes and the primary humanoid Animator rig from a modified FBX back onto a prefab, and generate `.hdiff` patch files for distribution.\n\n![Unity](https://img.shields.io/badge/Unity-2022.3%2B-black?logo=unity)\n![License](https://img.shields.io/badge/License-CC%20BY--NC--SA%204.0-lightgrey)\n![Version](https://img.shields.io/github/v/tag/PawlygonStudio/UnityTools?label=version\u0026cb=1)\n\n## Main features\n\n- Guided `Avatar Setup Wizard` available from `!Pawlygon/Avatar Setup Wizard`\n- Batch setup for one or many avatar entries in a single run\n- Shared-folder or separate-folder output layouts depending on your project needs\n- Automatic creation of working folders, copied FBX assets, copied prefabs, and working scenes\n- Reimport detection for modified FBX files\n- Review UI for matching FBX skinned meshes to prefab skinned meshes and replacing the prefab's primary humanoid Animator rig before applying replacements\n- Automatic creation of `FTDiffGenerator` assets for patch generation\n- `.hdiff` generation for both FBX and `.meta` changes using bundled `hdiffz` binaries\n- Optional prefab helpers for [Pawlygon VRCFT](https://github.com/PawlygonStudio/VRC-Facetracking) setup and importing the latest [PatcherHub](https://github.com/PawlygonStudio/PatcherHub) package\n- `FX Gesture Checker` available from `!Pawlygon/Tools/FX Gesture Checker` — scans an avatar's FX AnimatorController for gesture-driven facial expression transitions (`GestureLeft`/`GestureRight`) and applies a `FacialExpressionsDisabled` guard so they do not fire when face tracking is active. Supports per-transition and per-layer guards, work-on-copy mode, and full undo\n- `Eye Muscle Settings` available from `!Pawlygon/Tools/Eye Muscle Settings` — reads and adjusts the humanoid eye muscle limit settings (In, Out, Up, Down) on an avatar's ModelImporter for face tracking compatibility. Provides synced or split left/right sliders, live scene preview with bone rotation and blendshape activation, and writes changes back to the ModelImporter with a single click\n\n## Wizard workflow\n\nThe current workflow is built around a five-step editor wizard:\n\n1. `Setup` - choose source FBX/prefab assets, configure output folders, and create the working structure\n2. `Import Modified FBX` - replace the copied FBX with your edited version and wait for Unity to reimport it\n3. `Select Replacements` - review detected skinned mesh matches plus the primary humanoid Animator rig and choose which replacements to apply\n4. `Prefabs` - optionally add [Pawlygon VRCFT](https://github.com/PawlygonStudio/VRC-Facetracking) setup or import the latest [PatcherHub](https://github.com/PawlygonStudio/PatcherHub) unitypackage\n5. `Finish` - review the generated paths and completed output\n\nDuring setup, the wizard creates a working structure like this:\n\n```text\nAssets/\u003cMainFolder\u003e/\u003cAvatarName\u003e/\n  FBX/\n  Prefabs/\n  Internal/\n    Scenes/\n```\n\nIn shared-folder mode, multiple avatar entries can be placed into the same `FBX/`, `Prefabs/`, and `Internal/Scenes/` structure.\n\n## Diff generation\n\nThe package includes `FTDiffGenerator`, an editor asset that compares the original FBX against the modified FBX and writes patch files into:\n\n```text\npatcher/data/DiffFiles/\n```\n\nThe generator creates:\n\n- one `.hdiff` file for the FBX itself\n- one `.hdiff` file for the FBX `.meta`\n\nThe wizard creates these generator assets for you automatically as part of the avatar setup flow.\n\n## Requirements\n\n- Unity 2022.3 or later\n\n## Credits\n\n- [**Hash's EditDistributionTools**](https://github.com/HashEdits/EditDistributionTools) — Inspiration for distribution workflows using binary patching\n- [**hpatchz**](https://github.com/sisong/HDiffPatch) — High-performance binary diff/patch library by housisong\n- **tkya** — Countless hours of technical support to the community\n- **VRChat Community** — Feedback, testing, and feature requests\n\n*Thank you to everyone who helped make Pawlygon Unity Tools possible!*\n\n## License\n\nThis project is licensed under [CC BY-NC-SA 4.0](LICENSE.md).\n\nHDiffPatch (`hdiff/hpatchz/`) is distributed under the [MIT License](hdiff/hpatchz/License.txt).\n\n## Links\n\n- [Website](https://www.pawlygon.net)\n- [Discord](https://discord.com/invite/pZew3JGpjb)\n- [YouTube](https://www.youtube.com/@Pawlygon)\n- [X (Twitter)](https://x.com/Pawlygon_studio)\n\n---\n\n*Made with ❤ by Pawlygon Studio*","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpawlygonstudio%2Funitytools","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpawlygonstudio%2Funitytools","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpawlygonstudio%2Funitytools/lists"}
