Nothing happens when I am in edit mode with my mesh selected and hit U, then one of the options... I have opened a UV image window and created a UV map in the appropriate tab on the right... What have I done wrong? :O Thanks!
I'm having the same problem, and it seems to be a random thing. One time it works and the next it doesn't...even though I have nothing but a sphere in the viewport and I haven't changed anything about my layout or settings. What am I doing wrong here?
