"Caves , Mines & Underground Establishments"
It would be a really nice addition to Outerra.But?How would the developers of Outerra help you develop such things?... Well... They don't!
My idea is simple.
We need just the "entrance".
Let me elaborate on that.Well.. you remember that you can eventually go trough the ground?Well you see, that is the solution.We just need a tear in the ground to make the entrance.The entrance of a cave / deep mine or just an underground city.We can make those piece by piece, with stairs, or rock textures.We will just have to import it and build it.But we need some kind of tear in the ground so the terrain will go around it.Think of it like drawing with the "road" making tool, but the only difference you don't make roads.You make gaps in the ground, that can even lead you to the middle of the planet.But of course, I don't think you will go so far, that would be a long distance to go just with models imported of tunnels or elevators in mines.
My idea is a "simple" request for the future.Maybe it can be added to the "Road&Railway" tool, where you can simple have a "hole" maker tool that works just like the road one.
