Two quick questions: The walls snap to 90 degree angles, but the corners don't. I used the same base doodad for both. Is that information stored in the model itself? It's no problem, I'm just curious. Also, is there an all-black doodad I should be using? The boundary tile works well enough to demarcate the outside of the dungeon in game, but it doesn't look as good as a proper all-black border.
Lastly, because I'm annoying, a suggestion for the future: A standard two-wall width destructible wall for breakthroughs and stuff, and maybe a staircase built into the wall (to show where the in/out teleports are, although the doorway works well for that already).
