How do I install Nether 3.0?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

What Minecraft version does Nether 3.0 work with?

The listing gives Minecraft 1.20, 1.20.1. This is the version stated by the author or source site, not something we verified ourselves.

Nether 3.0

by kohara · on Modrinth

A light datapack which alters Nether generation to make it more interesting to traverse by modifying existing biomes.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

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.
