Description

Hello,

I've been experimenting with meshopt compression and rendering GLTF models in Mapbox. While `EXT_meshopt_compression` works fine, using models with `KHR_mesh_quantization` leads to rendering artifacts. I looked through the documentation and recent releases but couldn't find any mention of support for this extension. Since meshopt and quantization are often used together, adding this support would really improve compatibility and performance.

Any plans to include this in future updates?

Research direction

No files, tests, or entry points are named. Start by reproducing the rendering artifacts with a glTF model using KHR_mesh_quantization, then compare it with the working EXT_meshopt_compression path. Done means quantized models render without artifacts and support limitations are documented or resolved.
