: The conversion process can sometimes strip BlendShape data if not configured correctly. Verify that shape keys are preserved and mapped to standard VRM expression names.

Drag the newly created .vrm file back into Unity. convert+glb+to+vrm+better

GLB uses . VRM uses MToon (Color/Shade) . : The conversion process can sometimes strip BlendShape

A common mistake is trying to convert a messy GLB. To ensure a smooth transition: GLB uses

For batch optimization, tools like the Blender-3D-Batch-Optimizer can automatically downscale textures, apply smart compression, and re-export files with minimal quality loss while preserving format-specific features.

| Problem | Naïve result | “Better” solution | |--------|--------------|------------------| | Wrong bone orientation | Twisted arms/legs | Recursively reorient bones to VRM’s T-pose axes (+Y up, +Z forward, +X right) | | Missing blend shapes | No facial expression | Map GLB morph targets to VRM preset names (e.g., mouthSmile → AA ) | | Extra bones (wings, tail) | Discarded or broken | Keep as “unknown bones” under hips/chest | | No humanoid rig | Conversion fails | Auto-rig using heuristic (knee bend direction, shoulder spacing) | | Texture mismatch | Pink/missing materials | Convert glTF PBR → MToon (VRM standard shader) |
