I would think the easiest way to make a tunnel or a cave in, is to:
- lower terrain in appropriate shape and size.
- make sure the floor of it is ok.
- make a roof over it by using different appropriate templates, like rocks or similar.
- paint it over with trees and stuff to hide as needed.
Either that or making a small separate map and linking it to the bigger one.
- btw, is Ai grid now working alright?
Or do we still need to move the file manually?
