Here's both a transformed and the original GLTF. With the transformed GLTF the window shutters are misplaced. venice-transformed.zip

could be related to #235

I think this issue is unrelated to removing UVs and normals: upstream issue in https://github.com/donmccurdy/glTF-Transform/issues/1505 with details.

To be fixed upstream by https://github.com/donmccurdy/glTF-Transform/pull/1507. The cause of the bug was that glTF Transform's instance() function did not correctly handle files that already used glTF's GPU instancing extension, EXT_mesh_gpu_instancing.
