I’ve managed to share texture between all the minor straps. I usually don’t do this because it has a tendency to mess up with the normal mapping. But hey, it works.
This is definitely not my favourite UVmap. There is way too much empty space along the side panels, but at least I saved about a quarter of it with the texture sharing.
The harness is kind of this big mono-block thing so I had to cut int into pieces, hopefully no one will notice the texture seams.
There is still a bit of room I can use later for things like rivet backs and my logo.
