A naive conversion usually results in:
The reason: GLB supports arbitrary skeletons and shapes, while VRM demands a very specific humanoid rig with a standard bone set (hips, spine, neck, shoulders, etc.) plus a defined expression system. convert+glb+to+vrm+better
True better conversion is re-rigging, not remapping. A naive conversion usually results in:
VRM expects a specific humanoid structure with normalized bone scales, specific roll angles (e.g., upper arm roll 0°, forearm roll 0°). GLB often has arbitrary rigs. The reason: GLB supports arbitrary skeletons and shapes,
