Better Cave Worlds

This is Data Pack enables Cave World generation with biomes and allows foliage, aquifers, and large ore veins to generate. Unfortunately, you cannot change the height at which most structures generate with a Data Pack, so most of them generate on the bedrock roof. You should still be able to do everything you normally could, but it will be a challenge to do so!

Overworld and End

There is the regular version and a specific version for the End dimension. You can use both of these packs at the same time so that all of your dimensions generate as Caves.
