This topic has already been raised but the solution doesn't seem to work for me. I need to find a way to make the lines in a uv map evenly spaced.
There was an addon for blender 2.61 that would distribute the vertices on the horizontal and vertical axis https://developer.blender.org/T29981 but I'm not sure if it would work for 2.74. I read that using the uv sculpt smooth tool should work but nothing happens for me when I use that tool.
Does anyone have advice about how to evenly distribute vertices on the x and y?
