Hi Cesium,
I'm in the process of testing cesium with gltf datasets, for 3d-tiles-next.

My gltf files are compressed with EXT_meshopt_compression and KHR_mesh_quantization, using gltf-pack

I noticed support for these glTF extensions, is in progress...
#9520

I'm wondering, is there a preview of this, in a feature branch somewhere ?

Greatly appreciated.

Try setting Cesium.ExperimentalFeatures.enableModelExperimental = true before creating any tilesets.

We're in the process of refactoring the glTF loader and some new functionality like meshopt is behind this experimental flag.
