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 on the 26.3 port.

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

Categories:

• Terrain (world terrain) – v1.0.0+
• Caves (world cave generation) – v1.0.0+
• Biomes (biome settings) – v1.0.0+
• Vegetation (terrain vegetation) – v1.0.0+
• Ores (world ore settings) – v1.0.0+
• Structures (structure settings) – v1.0.0+
• Features (terrain and world additions) – v1.0.0+
• Blocks (replace and remove specific block spawning) – v3.0.0+

Since v2.0.0 you can change settings from the overworld, nether and end!

Then click “Generate Preview” to see a random seed using your rules of world generations

And finally you can import and export settings and by clicking “Open Settings Folder” a file explorer window will open with all your save files.

A new alpha feature just came out with a new world type so you can edit the world generation values in-game while the chunks update live to the settings you choose

Thanks for reading and using this mod!
