I just mean like..a quick cave on the side of a mountain or big enough indent to look like one. For some reason you can only cut terrain oer the entire vertical axis, but can't do it per pixel independent of that axis.

I just want to select a portion of terrain and get rid of it. Can't figure it out, if it's possible.


If you look at the D:OS campaign you will notice that Larian does this nowhere, so I would guess it is not possible. You can trick the player by doing a second terrain and connecting it with stairs or other walkable stuff and sorrounded it by mesh geometry. And then building cave walls and "occlusion" (via AI tab)
