Update: I've added animations to the people and now they have the same texture issue as the statue!

Ok, I think I got this fixed, thanks for the sample models, they render correctly for me now. It looks like the UVs for these models expect the texture mode to be repeated (which is the gltf/glb default.) So, I have updated the addon to have default teture wrap, please try out the latest version.
Also - can you point me at what tool created these models? I am interested in why the uvs are set this way.
