I "wrote" a script that generates a synthetic test asset that might be helpful here ("wrote" is quoted because the code is generated by GPT Codex, I've lightly reviewed the...

It feels like `EXT_mesh_gpu_instancing` should at the very least have a non-normative note saying that inconsistent scale sign (or maybe negative scale in general) is not supported well in renderers...

For testing, assets from this comment could be used: https://github.com/KhronosGroup/glTF/pull/2517#issuecomment-3440081285 (glTF-Sample-Assets will get...

For completeness, here's an updated version of the asset used by three.js 'webgl_loader_gltf_compressed' example; it can be copied to `examples/models/gltf/` folder to test this PR as well. (it seems better...

These extensions have not been merged; they are also multi-vendor, so support is not guaranteed. I have briefly looked at them in the past and it might make sense to...

I've seen the nested extensions in the prior EXT_ proposal but this one is the first KHR_ one so I'll comment here. I was very surprised to see the nesting...

I think the texture slots are not quite the same situation - these are nested objects with each individual object being extended, vs nested extensions that are being proposed here....
