About this Mod
Do you only want to slightly modify the Nether and not add a couple thousands of different mechanics?
Or do you just want some neat improvements to the Nether generation?
Or are you looking for a worldgen datapack that supports multiplayer? (including Bukkit/Spigot/Paper servers, etc.)
What does Nether 3.0 have to offer?
Increased World Height? You got this. The world height is now 192 blocks + 64 extra blocks for the roof!
It supports Multiplayer servers, no matter if it is Vanilla, or Bukkit/Spigot/Paper/Purpur/any other fork!
All biomes rehauled? That one was kinda obvious, but of course!
And yeah, that's all. Unlike my Ender Expansion pack - Stellarity - I want to keep the Nether rehaul simple.
