NEED HELP. Zmapper problems

PStrive

heres my problem when I try to use zmapper I get a notice that I have multiple UV regions. I dont understand why because when I imported my OBJ, all the verts were welded and I have 1 UV unwrap. anyways it tells me to click on "uv groups" and ctrl+shift to select the uvs I want to zmapper. So basically I have 2 questions

is there a way to combine these multiple uv regions? and when it creates the normal map it does not look the way the model looks at the highest res. there is some funkyness!?
thanks

tacit math

it'll flag that if you have any uv's outside 0 - 1. if that's what you intended to set up then yeah. you gotta follow those instructions it gives you and export multiple maps. otherwise it's back to your uv editor to make a few tweaks
