BONE REMAPPER
🚨 IMPORTANT — READ BEFORE PURCHASE !!! 🚨
🚨 BONE REMAPPER only works with characters that share the SAME skeleton/armature/rig!
🚨 SKINNED MESH ATLAS COMBINER only works with URP Textures!
BONE REMAPPER & SKINNED MESH ATLAS COMBINER
Two editor tools. One modular character pipeline. 🔥
Mix and match body parts, clothing, and accessories from different character sources — then combine them into optimized, atlas-packed FBX meshes ready for production.
The Problem
Building modular characters from multiple sources means dealing with incompatible skeletons, dozens of separate materials, and excessive draw calls. Manually remapping bones across 50–200 joints is tedious and error-prone. Maintaining one material per mesh part kills batching.
The Solution
Step 1 — BONE REMAPPER: Take skinned meshes from any source and remap their bones to your target character's skeleton. Drag, drop, click — done.
Step 2 — SKINNED MESH ATLAS COMBINER : Select all the meshes now sharing one skeleton, generate a PBR texture atlas across up to 6 channels, and export UV-remapped FBX files with a single material.
Result: Multiple character parts → one skeleton, one material, one draw call.
Bone Remapper — Features
Automatic bone matching by name between source and target skeletons
Bone grafting: missing bones are auto-created in the target hierarchy
Batch processing: remap multiple meshes in one operation
Drag & drop or manual mesh list management
Optional: move meshes into target hierarchy, delete old armatures
Works with Generic rigs — no Humanoid setup required
Full Undo support
Skinned Mesh Atlas Combiner — Features
SkinnedMesh Atlas Combiner uses Unity's official FBX Exporter, which can be installed from Unity's PackageManager.
PBR atlas generation across 6 channels (Albedo, Normal, Metallic/Gloss, Mask, Occlusion, Emission)
Atlas sizes from 2K to 16K with configurable padding
Visual grid layout preview before export
Reorderable mesh list with texture thumbnails and channel count
One-click export: atlases (PNG) + UV-remapped FBX + auto-generated material
Auto-detects render pipeline (URP / HDRP / Built-in) and assigns correct shader
Reflection-based FBX export — no mandatory package dependency
RGBA transparency support
