Overworldify
This is a silly cursed world generation datapack I have made that makes the Nether and End Dimension have the same terrain shape and height as the Overworld.
Notice: Not compatible with biome mods.
Currently not compatible with biome mods due to how this is made.
Additionally, due to the method needed for this worldgen to work, it is slow. I may make a fully modded version in the future that makes it generate faster.
Smart Adjustments
Further adjustments have been made to ores, structures, and features so that they work properly (e.g, ancient debris still generates most frequently at the bottom of the world).
Shout out to Apollo for discovering the technique to make this data pack possible!
