Hi, I have the same problem (macbook pro, M1 max, 32 GB ram). When exporting I always get gltf exporter errors:
Mesh xyz has some nearly zero-length tangents which may not be supported in some glTF applications. Consider checking ‘Recompute Tangents’ in the asset settings Material xyz uses mesh data from xyz but the lightmap UVs (channel 3) are nearly 100% degenerate (in mesh section 0). Simple baking will be used as fallback Material xyz uses mesh data from xyz but the lightmap UVs (channel 3) are nearly 100% degenerate (in mesh section 1). Simple baking will be used as fallback Maximum value (-1) used in indices accessor for mesh xyz (section ), this may not be supported on some glTF viewers Unsupported shading model (Two Sided Foliage) in material xyz, will export as Default Lit
