Adds the 1.18 cave generation (includes increased world height both up and down) and adds "hidden" biomes (lush caves and dripstone caves).

Adds it in a separate dimension so it WILL NOT overwrite your world.


It does use nether biome generation so it might be a little strange, but the biomes aren't too far away from spawn, so you should be able to find them.


Hold shift to use the given items to teleport you between the dimensions.


If you get stuck without the items you can type /reload.

If you don't have cheats and you get stuck without the items just open your world to LAN and enable cheats there, and you should be able to type /reload and have it work.


INFO: It uses a set seed (because that's how dimensions work 😑). If you're tech savvy you can modify the seed to be whatever you want in the JSON file under the data/sim_dimension/dimension directory. There's two instances so make sure to change both.
