terrain and sky mods

[3nk1dU]

Creating maps with extra mountainous regions by making dense patches of boulders and rocks, could be interesting, especially if rock objects could stack vertically. It doesnt seem like a +1 vertical exists, but there is some kind of -1 for underground belts.
Tall mountains could then make tunnels for trains and such an interesting feature.
Im thinking of modding the tank into a boat.

Finally, I'd like to run a clouds mod that is apparent above a certain zoom level. Each tile having a very tall range of potential cloud tiles. Possibly even a rain or snow thing.

The main idea is that a lot of potentially interesting mods require a 3D that exists partially with underground belts, but might be unnecessarily cpu intensive if implemented poorly. The terrain is one of my favorite things about the game. I like the idea of using everything or having to work with it, including the bodies of water and maybe the rain and wind and mountains.

Any thoughts?
