A major part of landscape generation is to allow for data to be stored on the up/down axis (Z), which allows caves and floating islands to be generated. However, the landscape tool doesn’t allow that and I was wondering how other game devs do those in UE5 (do they all use props to do it?).
Yes, caves and floating islands are separate static meshes.
What @Cleverlike_Studios said. The problem with Heightmap terrain is that it does not allow for things to be underneath or over. It’s usually one sided as well so being underneath allows you to see through it. A common tactic is to poke a hole in the terrain and place a static mesh there. So you’ll make the cave a static mesh, punch a hole in the terrain and mold the terrain around the entrance.
