Issues with quantized models

As far as I can see, nearly every model that I’m quantizing is reporting this warning:

quantize: Skipping TEXCOORD_0; out of supported range.

Then when I attempt to view the model, it loads but is invisible.

For example, with this unprocessed model: Car_csi4.zip

If I run

 gltf-transform quantize .\model.gltf .\model_quant.glb

This is the output:

warn: quantize: Skipping TEXCOORD_0; out of supported range.
warn: quantize: Skipping TEXCOORD_0; out of supported range.
warn: quantize: Skipping TEXCOORD_0; out of supported range.

warn: quantize: Skipping TEXCOORD_0; out of supported range.
info: model.gltf (1.39 MB) → model_quant.glb (1.06 MB)

And the resulting quantized model:

model_quant.zip

As you can see, there are a whole load of new errors.

If I run gltfpack on the original model all the errors are removed and it loads correctly.

Same, yes!

I think the draco errors are still occurring though

Between the ‘byteStride’ fix and cleaning up the empty accessors (https://github.com/donmccurdy/glTF-Transform/issues/259#issuecomment-846364403) it seems like Draco is working on my side now (tested with the car example) but maybe something else is different here, or it’s relying on the v0.11.1 changes… I went ahead and published v0.11.1, let me know if that doesn’t resolve it!
