The most noticeable difference between a low-effort and high-effort conversion is the face. GLB files use standard materials

A GLB uses "Standard" bone names (Hips, Spine, Neck). A VRM uses those plus special bones (LeftShoulder, RightToeBase) and requires specific scale constraints. A bad converter loses the connection.

Converting a GLB file to a high-quality VRM (Virtual Reality Model) involves more than just changing a file extension. Because VRM is a specialized sub-format of GLB designed for humanoids, you must ensure the model is properly rigged, assigned metadata, and configured for expressions and physics 1.
