Having played around a lot with worldgen in 40d and a bit in it here, I'm still in the dark as to how caverns are handled, and the wiki, while very thorough in describing what to expect from caverns, is a bit sparse on the subject of their generation. Thus, a bevy of questions:
1. How do they handle elevation changes? If I have a mountain next to a valley, will the cavern system(s) likewise adjust in height to match, at either a constant distance below the surface or a constant proportion of above-cavern to below-cavern space?
2. What about the magma sea? Does it too retain a constant elevation despite surface features?
3. How do the various variables for cavern worldgen interact, especially those for the Z levels that act as a vertical buffer between cavern systems? Are those buffers absolute, or in what fashion do they vary?
I suppose I'm just asking whether the caverns and magma sea are generated and the terrain dropped on top of it or if the terrain is generated and the caverns generated beneath them.
