I don't get it. I looked at the problem you were having and it made no sense to me. I even tried to reproduce the problem on my computer but could not.

I admit that I don't know a lot about UV sets but I thought that a UV could only exist in one set at a time. So, even if you took the pants and selected a group of UVs and put them in their own UV set, you couldn't also put them in another UV set at the same time... ?

You said there was something wrong with the UV Sets. What was wrong?
