Well i'm not doing exactly that, read too quickly ^^ I detach all shells that are in the 0-1 square. But it looks like you made the right thing. The only trick i use is from Jorge "Polytools" Rodriguez. I convert uvs to a trimesh, because mesh are faster to deal with than uvs, not to mention unwrap modifier. Also you could…
No problem! Wonder if there is actually a way to extract some sort of texture information. Like: - Do the faces IDs in the original mesh object have some sort of name? (they usually are 1 - No Name, 2 - No Name, etc... but MAAAYBE this time there is something). - Does it come with a pre-applied material? Standard?…
