• GLB (GL Transmission Format Binary): Often uses generic skeletons (e.g., "Armature," "Root," or custom bone names). It supports multiple meshes and mixed hierarchies.
• VRM (VRM Model): Is strictly standardized around the Humanoid skeleton (Hips, Spine, Chest, Neck, Head, Left/Right UpperArm, LowerArm, Hand, etc.). It was created specifically for VR/AR avatars.
