I am trying to figure out how to use the following GUI sprite sheet from open game art at http://opengameart.org/content/rpg-gui-construction-kit-v10 It is not a standard layout. I got it to work in XNA by creating a bunch of widgets. I am trying something similar with Unity, but having trouble. Is there a way to specify what part of the texture to use? Do I have to go in and "cut-up" the gui elements? Any input would be helpful.
