The two first pictures are a before/after using data transfer, look at those nice and clean rounded edges and those smooth welds 🙂
I’ve done some unwrapping on the low polygon mesh, it’s missing the logo, the lock adapter, and frankly it’s really not there yet.
I also made several attempts at auto unwrapping the high poly model, but due to some really bad seams, I guess I’m gonna end up unwrapping it manually :(. It is a bit of a pain because the model is a bit too dense. Live and learn I guess.
Last picture is a closeup of the low-polygon lock adapter, it looks already very nice, even without a normal map.
