Open up the Pack panel to find tools for the tight packing of UV shells to minimize empty texture space. Currently shells are only moved around in this process, so you may need to rotate some by hand for optimum packing.
- New Box
- This creates a new packing box around any picked shells. Shells can be place in or taken out of an existing box simply by dragging them with the usual Space-MMB combination. Use the Del hotkey to delete a box; moving all of the shells outside of a box will also delete it.
- Use the [ or ] hotkeys to repack the box under the mouse pointer. If no box is under the mouse pointer, then all shells and boxes will be packed into the 0-to-1 texture square.
- A box (and its contents) can be moved around using the Space-MMB combination on one of the its corner handles. It can be reshaped using Ctrl-MMB on one of these handles; this will also repack that box. Use the \ hotkey to rotate a box by 90 degrees.
- By default, boxes are free, meaning they will be moved around as required during the packing process. You can fix a box's position with the { or } hotkey; this will turn it from green to blue. Other shells and boxes will then be packed around that box, but it wont be moved itself. Use the same hotkey if you want to toggle it back to free moving.
- Delete All
- This will delete all boxes.
- Quality Fast/Mid/Best
- You will get slightly tighter packing with Best selected, but Fast' isn't too bad either, and is a lot faster. Mid is part way between the other two.
- Tile
- If you want your shells and boxes packed into multiple tiles, specify the dimensions of that tile grid here.
