Have you ever used an X-Ray Resource Pack? Have you wondered "Man, I wonder what it would be like if the entire world was actually like this."
...What do you mean no?
Well, I made a Datapack that does that anyways. The world looks completely normal except for the fact that most of it is missing... Only ores and the shell of structures are left in the world... You'll most likely spawn on a coal ore vein at y=0 in the middle of no where, stuck floating above the void. But hey! At least Diamonds are easy to find, right?
Shout out to Apollo for discovering the technique to make this datapack possible!

Not an x-ray mod! A datapack that makes normal worlds only generate air, except for blocks you would commonly see with x-ray.
