If your GLB uses complex shaders (e.g., hair shaders, anisotropy) or you need high-quality lit materials, Unity is superior to Blender.

When converting GLB to VRM, users frequently complain about quality loss. Here is how to fix the top five issues:

In the rapidly evolving world of 3D content creation, two file formats reign supreme in their respective domains: (the universal format for web-based AR/VR and games) and VRM (the standard for VTubing and metaverse avatars). As virtual YouTubers (VTubers) and social VR platforms like VRChat and Cluster continue to explode in popularity, the need to port high-fidelity assets from one ecosystem to another has become critical.

Convert GLB to VRM by importing the GLB into Blender or Unity, clean and retarget the model to a humanoid rig, fix materials and textures for PBR/VRM compatibility, and export as VRM with proper metadata and optimizations.
