Ugh, minetest is so fucked up. Finally found a terrain generator that isn't absolutely unplayable and horrible, and it doesn't generate any caves. And in fact no module in minetest/luanti generates surface caves. It's never been done, not in the decades of people working on that game.
Oh there are cave generators, but they always come as part of a terrain generator that leaves the landscape looking like a crumpled up blanket.
I can't write a cave generator. I make caves by picking a random spot, and randomly walking downward, avoiding too steep angles. You can't generate a random walk from the middle!
And they STILL do not support Simplex noise.
