The problem is: I have 1 mesh. I want some faces of the mesh to be in one map (faces A) and other faces of the mesh in another map (faces B). Now when I unwrap faces A, there is no problem, I get a UV map only with these faces. When I unwrap faces B to a new UV map, there is faces B and faces A on that map. While on the first map there is only faces A.
Is there a possibility to only get faces B on the second map or can I just move the faces A away?
In the file there is a plane. I first picked some vertices and unwrapped them with U -> Unwrap leading to UVmap1. Afterwards I picked some other vertices, created a new UV map with the + and then unwrapped them. Now if you select all and switch between the maps you will see that UV map 1 contains only the first vertices and uv map 2 contains the first and the second ones.
