Converting GLB to VRM: A Comprehensive Guide

Online GLB to VRM Converters (Use with Caution)

She added a simple spring bone to Moss’s tail so it would sway naturally when she moved her head.

• File > Import > glTF 2.0 (.glb/.gltf).
• Apply scale/rotation (Ctrl+A → Rotation & Scale).
• Check armature: remove extra bones or constraints that conflict.

• Failed humanoid mapping: rename bones to standard names and reconfigure in Unity Avatar Editor.
• Broken shape keys: ensure no mesh modifiers change vertex order; re-import original GLB if needed.
• Materials look wrong: unify to Principled BSDF in Blender or adjust shaders in Unity.
• Scale/rotation mismatches: apply transforms in Blender before exporting.

1. Import: Import the .glb file into Blender (File > Import > glTF 2.0).
2. Scale Correction: Ensure the model is real-world scale (usually ~1.6m height). Apply Scale (Ctrl+A > Apply Scale).
3. Bone Check: Verify the armature hierarchy. VRM requires specific bones (Hips, Spine, Chest, Neck, Head, etc.).
4. Blend Shapes: Rename blend shapes to standard VRM naming conventions (e.g., Blink, A, I, U, E, O for vowels).
5. Export: Export as .fbx or re-export as a clean .glb to import into Unity.

• Ensure the model is a humanoid mesh with a skeleton. If it’s not skinned or rigged, you’ll need to rig it in a 3D editor first.
• Check textures and materials: VRM supports glTF PBR; complex non-PBR shaders may need simplification.
