So i have a human body and i want to unwrap the head (one polygroup) on the -1,1 Uv space and the body (another polugroup) from 1,1. Is there a way to do this without me separating the mesh in two different ones?
Thanks in advanced!
UV Master is capable of mapping to only one UV space. You would need to split the mesh.
I was afraid of that! I guess theres something more for the guys at Pixo to work at! 
hehe
Thanks for the reply aurick!
Hi there
I use Zbrush combined with Lightwave for UV Editing…If you have a separate 3D Package with a UV editor like most packages do…you could export your individual sub-tools(parts) as OBJ’s each of them with their own UV Map created and then merge them back in your host 3D Application.
You might interested in this video I made as it covers the UV Master plugin in great detail.
