How to install Minecraft Data Packs

WARNING: DO NOT ATTEMPT TO INSTALL THIS ONTO AN EXISTING WORLD.
This datapack makes the nether generate under the overworld. No teleportation tricks, both generate in the same dimension at the same time. The world height is expanded by 144 blocks, ranging from -80 to 448. This pack will likely not be updated.'
This pack is officially deprecated. I will no longer update it.

Features that work as intended:
- All nether biomes generate with minimal issues
- Bastions generate
- The nether bedrock ceiling and the overworld bedrock layer have become obsidian
- Nether and Overworld ore distribution work (mostly)
- Most of the overworld works as normal

Features that don't work as intended:
- Fortresses do not generate (Blazes now spawn in basalt deltas, Wither Skeletons in Soul Sand Valleys)
- Water can be inside the nether
- The overworld sky can be seen in the nether
- Strongholds don't generate correctly, have been replaced with a naturally spawning portal room

Warning: This is incompatible with other worldgen packs, including my other tech demos.

Multiple fixes : by Apollo404 06/20/2022 12:48:13 amJun 20th, 2022

- Fixed biome distribution at very high y-levels. This ended up requiring me to modify nether biome placement.
- Fixed snow not appearing in snowy biomes (it's 97% fixed, still some minor issues near water)
- Added a function that deletes all nether portal and water blocks around the player

Sad to see that it's not getting updated anymore, I'd love to see a version for 1.20. Great pack, and great work!

Also hi from CaptainSpooklez.

So does this invoke the original nether generator, or does it replace it? The reason I ask, is because I already use a Data pack, that replaces the nether generator, but answers calls for the nether generator. So what I still be able to use that other data pack with this?

The nether still technically does generate and you can teleport to it, but the nether below the Overworld is a separate thing that datapacks wouldn't be overriding.
