Description

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.

Compatibility

Before 1.20, if you want to play this mod with other mods that add biomes (for example, BYG and Emerald Craft), you need to install Ocean Blender as well.

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.

Examples/Presets

Here's some presets of config file.
