Technical Details

Key standards include:

  • VRM 1.0: glTF2.0-based format with humanoid-specific extensions for expressions, gaze control, and standardized rigging

  • Scale and Orientation: 1.00 = 1m, Y-up, -Z forward, Unity Humanoid compliant T-stance

  • Single File Packaging: All data including textures and materials in one file

  • Licensing Metadata: Title, author, modification/redistribution rules (Creative Commons), and usage permissions

    Standardization Progress (2024)

    Khronos Group and VRM Consortium collaboration (October 2024) advancing VRM as official glTF extensions. Successful ratification would elevate global recognition and encourage broader platform support.

    Industry Adoption

    VRM established as de facto standard in Japan since 2018, supporting VirtualCast, VRoid Studio, and cluster platforms. Decentraland enabled VRM exports (July 2023) for use in OnCyber, Hyperfy, and Monaverse.

    Avatar Translation Framework

    Metaverse Standards Forum working group developing common baseline format for mesh, material, skeleton, animation, physics, and metadata translation across platforms.
