Here is a issue that I keep getting, tried to unwrap this part of my object as a cylinder and also tried a normal unwrap along with many off the other options, it has seams but my unwrap is bending and not relaxed at all for a simple shape. Pretty much unusable.
see image attached.
note there is no back faces
I know i can use the align tools but i have quite a few objects like this so it would take much time.
If necessary tweak it’s UV so it’s perfectly straight (rectangle). One way is to scale the 2 top UV-vertices to 0 on y-axis, then bottom 2 vertices, then the 2 left vertices on x-axis, etc.
In edit mode in 3dview, select all vertices (A) with the unwrapped face as the active face.
Then ‘U’ -> ‘Follow Active Quads’ and choose ‘Length’
