Basically, I'm thinking of something that works in the reverse of a pump, that would automatically fill a large area with water, creating lakes and that. I've heard of teraformers but I do not know how customizable they are.
I may loathe Blutricity, but this sounds like a good option.RP2 pumps can do that. Place a grate at the level you want the water. Connect the pump to a tank with an infinite water source and turn it on.
That would be bad, considering my base is dug out like this.Just remember to also enclose in the area and don't leave any caves open either, otherwise your cave system around that area will also be filled with water up to the height of the grate..
filler, ice, wrath lampAny way to do this in a contemporary pack which doesn't have RP2?
