Introduction:

JJThunder Hell is Fire, is a datapack that terraforms the nether into 2032 block world, allowing it to contain all 3 world generation types:

  • Caves: Cave-like terrain that occupies the bottom-half of the dimension
  • Overlands: Overworld-like terrain that starts at around y=1000
  • Floating islands= End-like terrain that starts at y=1500

Notes:

  • Allocate more RAM depending on your render distance.
  • Do not use the data pack in an existing world as it will destroy it.
  • Not compatible with other world generation data packs or mods derived from data packs like incedium.
  • Compatible with world generation mods like better nether, byg, regions unexplored with limitations (Not Tested, so please give it a try and validate if needed).
  • Donwloading performance mods is highly recommended, as any world height increase world generation datapack reduces performance
  • Ore generation remains untouched. Please let me know if ores only generate till y=128 only.

FYI:

  • Floating islands contain unique and massive caverns different from bottom caves, so don't hesitate to explore.
  • Must use shaders to unlock its full potential. I myself use BSL shaders and render fog on a further distance without completely eliminating them.
  • No photos are taken for now. However, if any videos are released featuring this data pack, I will feature them here. (Only ones that are well done will be featured)
  • I have included the datapack for all versions ranging from 1.19 to 1.21, however, backporting to earlier versions isn't possible.
  • This is a 1st iteration of the data pack, so feedback may be needed.
