This is the story of "The Great Transformation," a journey of a static 3D model becoming a living digital soul. Chapter 1: The Birth of a Shell

If your model looks "exploded" or has weird textures after conversion, ensure all Transforms (Location, Rotation, Scale) were applied ( in Blender) before you started the export process. for hair physics specifically? VRM format / VRM Add-on for Blender

If your GLB is not rigged, you must rig it using Mixamo or the VRM Auto-Rigging tools. 5. Export to VRM Go to File -> Export -> VRM (.vrm) . In the export settings:

Click . Ensure Unity has correctly mapped your model's skeleton to the standard humanoid bones. If any bones are missing or misaligned (marked in red), manually drag the correct bone meshes into their respective slots. Click Done . Step 3: Normalize the Model

Before diving into the conversion process, let's briefly discuss the GLB and VRM file formats.

If you prefer using Unity (for VRChat compatibility), you can use the UniVRM package. Import your GLB model into Unity. Use the VRM -> Import function.

Drag your humanoid GLB model from the Project window into the Hierarchy scene view.

Built on top of the glTF/GLB standard, VRM is an open-source file format specifically designed for 3D humanoid avatars. It standardizes bone mapping, blend shapes (facial expressions), physics (spring bones for hair and clothes), and privacy settings/licenses directly inside the file metadata.

Inside the VRM panel, click "Create VRM Data". This creates the root node for VRM settings.

: If your model is in an "A-Pose," many VRM-compliant apps will display it with broken shoulders. Always enforce a T-Pose during export.

Adjust the sliders to test how the face deforms during tracking. Step 5: Export to VRM Go to File > Export > VRM (.vrm) .

Go to the top menu in Unity and select (or VRM1 depending on your package version).
