THE DETAILS:

Alright so. I really like the vertical challenge of the AmpXtreme data pack, but I really want the lower half of the world to be densely modded ocean exploration. Majority of what you think of for deep sea exploration overhauls down there, organized into "shelves". That way it's not just oops all ocean for 80% of the way down and then on the floor everything generates. It's spread across the entire process.

Up there would have structures but I can't be assed to illustrate them. You'd have part of the game hooking or gliding or jumping or climbing around on the upper half, and then diving down to explore the bottom half. Nether? I dunno, at the bottom? Who knows.

So yah if you've experimented with something like this idea before tell me your results. And if you know that theoretically this is possible, recommend mods for making it very, very fun. Thank you for your time.

If such isn't possible, I'll start chiseling away at it on my own time. No other choice.
