I have noticed that almost nobody have a visible progress of a cave map. It would be awesome if someone does the cave adventure map where's many branching cave tunnels and huge caverns. There's one little tunnel on the grid map, but it's not enough
As of right now, it's not possible to make caves with the world editor, as they have no collision. They few caves and tunnels in existence right now were made with a 3D model, or some other method.
