VRM supports PBR (Physically Based Rendering) and MToon materials. Your textures should include:
If the character remains locked in a static pose and refuses to animate in streaming software, the engine did not register the asset as a humanoid. Ensure the Rig Type is explicitly set to Humanoid rather than Generic or Legacy prior to exporting. Best Practices for Optimizing VRM Avatars
Download the package (.unitypackage) from the official VRM consortium GitHub page. convert glb to vrm
If your character appears entirely white or untextured after conversion, your GLB textures may not have been embedded correctly, or the shader used is incompatible. In Unity, ensure your materials are extracted from the asset and switched to standard VRM shaders like VRM/MToon . Twisted or Distorted Limbs
Method 1: Converting via Blender (Recommended for Complete Control) VRM supports PBR (Physically Based Rendering) and MToon
We can look into standard in Blender to reduce your GLB file size before attempting a VRM export.

Select it to configure components like VRM Spring Bone (add hair or clothing transforms here to give them physics).
Under the section, you will see a list of standard VRM bones (Head, Neck, Spine, Hips, Left Arm, etc.).
A VRM is essentially a GLB file with specific extensions and a stricter humanoid specification. Recommended Conversion Workflows (2026) 1. Professional Method: Blender with VRM Add-on
