GLTFLoader plugins for loading Meta Avatars

This project is in an experimental state

Usage

See example/index.html for an example of how to use this.

The avatar .glb files contain multiple versions all with names matching S0_L[0-4]_M[01]_V[01]_optimized_geom. The meaning of each segment: | Segment | Meaning | | -- | -- | | S0 | Unknown | | L[0-4] | Lod level, 0 being the highest and 4 the lowest | | M[01] | Model type, 0 being full body and 1 being upper body only | | V[01] | Viewer type, 0 being first person (no head geometry) and 1 being third person |

For example: S0_L0_M0_V1_optimized_geom will be the highest detail (L0), full body (M0), with head (V1).

Limitations

• Meta Avatars appear to have two color vertex attributes, neither seem to provide correct output when taken as-is, so vertex colors are disabled.
• The normals and tangents aren't dequantized yet.
• It assumes that the KTX2 texture is of a specific format and that the browser supports this natively (no transcoding is done)
• Textures for avatars intended for the Rift can't be loaded
