About Custom World Generation
From ModrinthCustomize your terrain, biome and structure generation
Abstract
This mod is separated from Ocean World. You can customize terrain generation, biome generation and structure generation with this mod.
How to use
Install this mod. Server side is required while client side is optional (no effect whether install in client side or not).
Edit custom_worldgen-config.json in "config" folder in your game directory at server side (for single player, this is located at ".minecraft/config"; for multiple player, this is located in "<server directory>/config").
Following the guide in custom_worldgen-config-readme.md. You can also use Ocean World Config Generator to help you do this.
Examples/Presets
Here's some presets of config file.
Compatibility
Before 1.20, if you want to play this mod with TerraBlender together, you should install it with Ocean Blender.
After 1.20, ocean blender is merged into this mod so you don't have to install any other mod else.
I have to say that all biome mods except BOP can work with this mod together. I tried to contact with the author of BOP, but he seems not to want to fix this compatibility issue.
