Assign bone chains for elements that should move naturally, like hair, skirts, or capes.
Assign the root bones of your character's hair strands, skirts, or dangling accessories to the root bones array.
High-quality avatars need natural movement for hair, clothing, and accessories. Select the root of your imported avatar in the hierarchy. Add a VRM Spring Bone component. convert glb to vrm high quality
Drag the model into your scene hierarchy. Select it, go to the top menu bar, click VRM0 > Export to VRM (or VRM1 depending on your target application). Fill out the required metadata fields (Title, Author, Version).
Converting a 3D model from GLB format to an optimized VRM avatar involves more than just changing a file extension. Whether you are prepping an asset for VTubing, the metaverse, or interactive games, maintaining texture resolution, rigging integrity, and proper materials is essential.
: VRM enforces a strict humanoid bone structure, making animations seamlessly cross-compatible. : Download and install a supported Unity LTS
: Always use MToon for the best lighting and outline results in VRM-compatible apps.
Select your imported model in the project window, go to the Inspector , and set the "Animation Type" to Humanoid . Click "Configure" to ensure all bones are mapped correctly. 3. Materials and Shaders
In the top menu bar, go to VRM0 > Export UniVRM or VRM1 > Export . Drag the model into your scene hierarchy
By following this guide, you will transform a generic GLB file into a production-ready, expressive VRM avatar that rivals custom-made VTuber models—retaining every polygon, every pixel, and every animation curve from the original source.
Adjust the , Gravity Power , and Drag Force to achieve fluid, natural secondary physics. Step 4: Exporting the Asset Select the top-level GameObject of your avatar.
A GLB file is essentially a static or animated 3D mesh. A VRM file is a specialized version of the GLTF standard (which GLB uses) that includes specific metadata for:
