Crucial: If your model lacks finger bones, leave those slots empty. Incorrect mapping causes tracking software to distort the mesh. Step 4: Configure BlendShapes for Expressions

| Issue | Likely Cause | Solution | |-------|--------------|----------| | Model appears with missing textures | Relative texture paths broken | Embed textures in VRM or ensure correct path mapping | | No facial expressions | BlendShapes not mapped to VRM expression names | Map shape keys to standard expression names (happy, sad, angry, surprised, neutral) | | Bones incorrectly positioned | Skeleton hierarchy doesn't match VRM standard | Rebuild skeleton or remap bones using bone mapping tools | | Export fails (bone count issue) | Too many bones or non-humanoid bones included | Remove unnecessary bones or split model into multiple files | | Animation issues after conversion | GLB animations not compatible with VRM rig | Re-target animations in Unity before export | | "Command not found" (CLI tools) | PATH not updated after installation | Run ./setup_global.sh or add ~/.local/bin to PATH manually | | Model looks different in VRM viewer | Shader incompatibility | Convert custom shaders to MToon in Blender prior to export | | File too large for upload | Textures too high resolution or too many polygons | Downscale textures to 512-1024px, use mesh simplification tools, prune unnecessary animations |

❌ Convert and lose all facial expressions ✅ Better: In Blender, rename shape keys to VRM preset names ( Neutral , Joy , Angry , Sorrow , Fun ). The VRM exporter will map them automatically. convert+glb+to+vrm+better

This resets your scale to 1.0, and position to 0,0,0, preventing massive distortion during export. Phase 2: The Best Conversion Workflow (Unity + VRM UniVRM)

Define the "FirstPerson" bone (usually the head) to prevent your camera from looking inside your avatar's head. 4. Finalizing in Unity (The "Best" Way) Crucial: If your model lacks finger bones, leave

If your GLB uses complex procedural Blender materials, bake them down into static 2D image textures (diffuse/albedo maps).

: Standard GLB materials often look dull in VTubing apps. Replace them with The VRM exporter will map them automatically

MToon shaders allow you to mix shading colors. Set a custom shadow color so your character looks vibrant even in dark virtual environments.
