About This Tool

This tool enables reliable conversion between VRM avatars and common 3D formats to support asset portability across engines and platforms. It processes the VRM extension for rig and morph compatibility, preserving texture references and animation data when requested.
Conceptually, the system parses input assets, validates structure, maps humanoid rigs to target rigs using standard bone roles, and rewrites mesh data into the target format. It does not perform artistic edits; it focuses on structural compatibility, unit consistency, and asset health checks.
Who benefits: 3D artists, game developers, AR/VR teams, and metaverse builders who need to share avatars between Unity, Unreal, Blender, and web viewers. Unique value includes automated bone mapping, optional animation retention, and batch-ready API for pipelines. Use cases include porting VRM avatars to GLTF for web viewers, conjugating assets back to VRM for avatar ecosystems, and ensuring consistent morph targets across engines.

How to Use

Provide inputs: upload a VRM file or select source/target formats.
Configure options: enable or disable animation retention, set scale_factor, and decide on texture export.
Run conversion: start the process to produce a target-format asset.
Retrieve outputs: download the converted file and any validation report.
Validate in your engine: import the asset to verify rig, morphs, and textures.

Frequently Asked Questions

Find Quick Answers

What formats are supported?

The tool reads VRM avatars and outputs to GLTF/GLB, with the ability to ingest GLTF/GLB and export VRM where feasible. Additional formats may be supported via backend capabilities. Conversions prioritize geometry, textures, and correct bone roles; some formats may require intermediate steps.

Are animations preserved?

Animations can be preserved if you enable preserve_animations. Compatibility depends on target format support and bone mapping. If the target lacks required channels, animations may be simplified or discarded, with a detailed report indicating affected clips.

How to resolve bone mapping issues?

If bones or morph targets do not align after conversion, verify target format support for humanoid rigs, adjust scale_factor, and re-run. Review the validation_report for mapping notes and consider alternative target formats if needed.

Does it modify textures or materials?

Textures are preserved by default; materials are mapped to engine equivalents where supported. If export_textures is disabled, textures will not be exported; some material properties may be approximated during conversion to maintain visual fidelity.
