Blender Version
Broken: 2.71
Worked: 2.68

Short description of error

UV projections are distorted

Exact steps for others to reproduce the error

Take standard cube, change its dimensions to 1:1:0.075, object mode, apply scale, edit mode, smart UV project, and it is distorted, that is the 2 big faces are not squares, they are rectangles. At least when texture size is 1024*512.

Second error, draw other objects option in UV/image editor does not work.

Exact steps for others to reproduce the error

I unwrap one cube, go to object mode, select the cube I already unwrapped and shift select new cube to unwrap on the same image, go edit mode, hit unwrap, go to view >>> draw other objects and outlines of the first unwrapped cube do not show up.

All above bugs do not appear in Blender 2.68 version

Point 1 Not quite sure this is a bug, afaik this unwrap script does not ensure proportions are kept? Campbell should know…

Point 2 no bug here, since your two objects have same unwrap… just move active one, you’ll see the other is there.

Yes mont29 you are right, second issue is not a bug as it turns out, but I clearly remember working on another project and it did not show up, I was moving UV around, but it seems I cannot recreate that now, anyways thanks for pointing out.

As for the first point, it does ensure proportions are kept at least in blender 2.68.

Just figured out, that problem #1 does not work correctly in cycles, when you switch to blender internal, it does not have distrotion issue!
