Convert+glb+to+vrm+better -

VRM uses a specific (the rotation of the bone on its axis). GLB models exported from programs like Cinema4D or Maya often have "Z-up" forward axes, while VRM uses "Y-up."

Stop settling for broken FBX conversions. Do it better. Do it in Blender. Share your model's origin (VRChat, Sketchfab, Daz3D) in the comments, and we'll write the custom shader mapping for your use case. convert+glb+to+vrm+better
