OMI glTF Transform

Command line tool and node.js/browser library for transforming glTF files with OMI glTF extensions.

Supported Extensions

• MOZ_hubs_components
  • audio
  • audio-params
• OMI_audio_emitter

CLI Usage

Currently the CLI tool converts the audio/audio-params MOZ_hubs_components to OMI_audio_emitter. It does not support other extensions at this time.

The general use-case is to convert from a file exported from Mozilla Spoke or the Hubs Blender Addon to the OMI standard extensions.

Ex. Convert From Exported Spoke glb to OMI glb

npx omi-gltf-transform ./spoke-export.glb ./omi-output.glb

Ex. Convert From Exported Spoke glb to OMI gltf

npx omi-gltf-transform ./spoke-export.glb ./omi-output.gltf

Library Usage

The following classes and functions are exported from the library and can be used in more complex gltf-transform pipelines.
