Editable World Generation

This mod allows you to edit almost every rule of Minecraft's world generation. From biomes, to structures, to terrain & caves to even surface decoration. More versions soon! Working up from 1.20.1 all the way to 26.2 so stay tuned...

Start by selecting the "Custom" world type and then click "Edit rules"

After you do, you will be thrown into the editor where you can edit the world generation rules that make up the world
