EN 1. Kawasa BlendShapes - Region hider for VRChat avatars 2. Turn a blend shape into a real toggle - Kawasa BlendShapes 3. Kawasa BlendShapes - split mesh regions into toggles PRODUCT DESCRIPTION (paste everything below) ════════════════════════════════════════ Pushing a blend shape to 100 deforms the mesh - it does not remove it. Kawasa BlendShapes is a Unity editor extension that makes any part of a VRChat avatar disappear completely with one click, and turns it into a menu toggle you can actually switch. ■ Sound familiar? - You want a hand or foot gone, but at weight 100 the mesh is still there - You only need to toggle one part of an outfit - Splitting meshes by hand for every toggle is tedious - The hide animation you made does not play in VRChat - Every hidden part adds another blend shape you have to manage ■ What it does It splits the faces touched by a blend shape out of the original mesh into a separate child object. The original mesh keeps the rest, so expressions and blinking keep working. Visibility is driven by the GameObject active state (m_IsActive), which previews, records and plays back reliably in VRChat. In short: instead of a permanently maxed blend shape, you get a hidden region you can toggle from the menu. ■ Features - Hide region Splits the faces touched by vertices moving past the threshold (default 1 mm) into a child object - Restore / Restore mesh Merges split regions back into the original mesh - Multi-select Checkbox selection across shapes and renderers - Batch weight editing Drag the slider and every selected shape follows live Supports 0 / 100 / any value from 0 to 100 - Key weights Keys the current weights of the selection into the current frame - Key into clip Writes the m_IsActive curve into the current clip when splitting - Trim unused shapes (automatic) Removes every shape that never moves this mesh's vertices - Remove selected shapes (manual, multi-select) Deletes chosen shapes, with an automatic backup first - Undo remove Restores the previous deletion, one step at a time - Inspect clip Dumps every curve of the current clip (path / property / key count) - Clean generated Deletes unused generated meshes in one click - Assign mesh (recovery) Puts an original mesh back if you overwrote it by accident - Three UI languages 中文 / English / 日本語, one click to switch - Undo-friendly Weight changes, splits, restores and shape deletions all support Ctrl+Z ■ How to use (3 steps) 1. Select the avatar in the Hierarchy and open "Kawasa → Kawasa BlendShapes" 2. Click Hide region on the target shape → the affected faces become KawasaHidden_<ShapeName> → an m_IsActive = 0 key is written into the current clip 3. Put that clip on an FX-layer state in the Animator → ON hides, OFF shows. With Write Defaults enabled on that layer, turning it off restores the default automatically ■ Requirements - Unity 2022.3 LTS (developed and tested on 2022.3.22f1) - VRChat SDK3 / Avatars 3.0 - The mesh must have Read/Write Enabled (FBX → Model tab → Meshes → Read/Write Enabled → Apply) ■ What's included - Kawasa_BlendShapes_1.0.0.unitypackage └ KawasaBlendShapes.cs (the editor tool) └ KawasaBlendShapes.Editor.asmdef (Editor only) └ Icons in four sizes - Manuals (日本語 / English / 中文) * Avatar models, outfits and textures are not included * Editor-only tool - it is never included in a VRChat build ■ Notes - This is a Unity editor extension; no model data is included - Use at your own risk - Redistribution, resale and claiming authorship are prohibited - For use on the buyer's own avatar modifications only - Results may vary depending on Unity version and model structure - Please report issues via message ■ Good for - Gloves on / off - Toggling outfit parts (sleeves, hems, ornaments) - Kemono ears and tails on / off - Swapping ear accessories - Temporary part hiding for gimmicks ■ Changelog v1.0.1 (2026-11-08) - Initial release - Region split / restore, multi-select, batch weights, animation keying, shape removal and undo, three UI languages
