About this project

What does Flat Biomes add?

This mod adds a way to enable biomes on vanilla flat worlds, which means you get to have biomes while also modifying the built in layer preset of vanilla minecraft.

There are 3 biome presets, type the one you want here: (World -> Customize -> Presets)

The presets are:

  • flatbiomes:overworld
  • flatbiomes:nether
  • flatbiomes:end

The latest version was tested on all versions 1.21.3 to 1.21.10 but will likely work for future versions as well

(Does not work on 26.1)
