Invalid KHR_texture_basisu usage in AnisotropyBarnLamp.gltf #117

Closed donmccurdy closed 1 month ago

donmccurdy commented 2 months ago

In the AnisotropyBarnLamp.gltf sample, the .ktx2 textures are embedded without the required extensions:

Compare to the examples in the spec. A quick way to fix this is to read/write the model with glTF Transform, which will automatically append the missing extensions:

gltf-transform cp input.gltf output.gltf

That's what I get for editing raw JSON. Thanks for the issue!
