+ | ; Unstack Overlapping : If you have overlapping shells, but don't want them to be, then click this button and they will be moved across, then up if need be, to empty locations in adjacent UV tiles.

+ | |||
+ | ; Lock All To Tile : Shells wont be moved outside of their current tile during packing. Ticking this option affects all shells, or you can use the '''#''' hotkey to apply the locking selectively to shells and boxes. | ||
