Change mesh UVs without affecting clones

[joostVanhoutte]

I'm trying to change the UV attributes of a mesh, but I need clones of the mesh to keep their own UVs.

As you can see in this example, both meshes get their UVs updated:

I tried cloning the attributes but that didn't work:
child.geometry.setAttribute('uv', child.geometry.getAttribute('uv').clone())

Also, I can't use a texture offset because then I'd need to clone the texture for each mesh and that causes a significant hitch.

Cloning the geometry works.
