I did like the "look" of the dungeon area caves. My reason for making wall tiles that look like mountain tiles is because I don't really care for those thin curved things that they use for cave walls by default.
But, I tried placing mountain walls at -20z but they vanished when I painted over the top of the cave with WF....or, it looked like there was a major dip in the landscape where the cave wall was below ground level. ::shrug::
Maybe I will just stick with what I did before; just put a teleport tile at the cave entrances and put my caves in the dungeon area. That way, too, it can be always dark and I can light them with torches - which is what I also did before. It makes the caves look more realistic, I think.
Dian - I'm using Sphere & Dragon. I've yet to try out RunUO. But, I might give it a shot, too, just out of curiosity.
Thanks for the replies, guys.
