A GLB is a snapshot of a model. A VRM is a system . Spend 70% of your time fixing the armature orientation and eye blendshapes inside Blender. Once you dial in the T-Pose and rename your shape keys using CATS, the export button becomes trivial.
Converting a GLB (Binary glTF) to VRM isn't just about changing a file extension; it’s about transforming a generic 3D asset into a fully expressive, interactive avatar. While many online tools offer "one-click" conversions, doing it requires optimizing bone structures, mapping expressions, and managing physics for a professional result.
