making a hole in landscape ?

So if I fill the level with landscape , how can I create through the landscape, like say a cave or dungeon that goes down?

I’ve found a nice 4 Min Tutorial on youtube for this. It’s about masking out parts of the terrain. And for the cave I would use some static meshes, which could be made in blender or downloaded from the ue marketplace etc. (modular walls,stones or whole dungeon system)

This explains it pretty well!

Sorry, I’ve forgotten to give you the link, but lc.heslinga has provided it already.

yea it looks good , i’m gonna check it out , thanks
