Very interested in the new .gltf enhancements (especially instancing)! Are there any plans on file compression as well? I’ve been using this to compress .glb files but wonder if it might not be compatible with PlayCanvas in the future https://github.com/pmndrs/gltfjsx

The ones that I know can work is Draco and MeshOpt. At the moment, neither are done on our backend when we convert FBX to GLB

But if you are loading a GLB directly, Draco example: Loading Draco Compressed GLBs | Learn PlayCanvas and MeshOpt example: https://playcanvas.com/project/952969/overview/ktx2-glb
