"Chimera Hair Master" — The all-in-one tool that unifies, recolors, and even reshapes your hair chimera!

"These hair colors just don't match..." "Tweaking shadow settings to match is such a pain..." "The hair pieces are slightly misaligned with each other..."

🦈 This tool might just solve all those problems!? 🦈

Two Unity Editor extension tools that help with hair chimera creation and mask painting for VRChat. Instantly fix the mismatched-color problem when combining multiple hair assets. It also integrates meshes and materials to improve performance. On top of that, mask texture editing now stays inside Unity from start to finish — no more bouncing back and forth with external paint software! Let's make those tedious hair chimera tasks just a little bit easier!!!

〇 Chimera Hair Master

Solves the "color inconsistency", "mesh & material bloat", and "mismatched material settings" issues that come with making hair chimeras for VRChat avatars.

◆ Color Matching

• Hue Shift Mode: Changes only the hue while preserving shading details
• Gradient Mode: Completely replaces light/dark with a gradient curve
• Saturation/Brightness preservation adjustment
• Brightness Unify Mode (matches to the brightest/darkest texture)
• Per-renderer fine brightness adjustment
• New: ability to ignore color matching for areas specified by a mask

◆ Mesh Integration

• Automatic texture atlas generation (supports 512–4096px)
• Per-UV-island placement adjustment
• Bone integration & rebinding
• Selectable integration target by renderer / sub-mesh
• Parts filtering via the Mesh Cut function

◆ Mesh Deformation (new from v1.1!!)

• Move and reshape individual hair parts
• Deform registered hair shapes with mouse operations
• Export deformed hair as a new mesh

◆ Material Setting Unification

• lilToon shader compatible
• MatCap texture unification
• Probe Anchor & Bounds settings

〇 Mesh Deformation Tool (standalone use of the above feature)

• Mesh deformation by UV island, vertex, or lattice
• Symmetric deformation (left/right, front/back, top/bottom)
• Export as a new mesh
• Non-destructive deformation via NDMF

〇 Mask Creation Helper Tool

A tool for editing shader mask textures (2nd color blend, shadow masks, etc.).

Prerequisites
