## Overview **Biome Replacer** lets you control biome distribution without changing terrain generation. Replace any biome with another while preserving the landscape's shape and only changing biome-specific features like colors, mob spawns, and vegetation. ### Use cases: - Remove unwanted biomes - Configure worldgen datapacks like Terralith - Fix mod compatibility issues - Enhance almost-perfect world seeds - Create custom world experiences ## Features - **Easy configuration:** Simple properties file with intuitive syntax - **Negligible performance impact:** Runs only once, and does not slow down the generation - **Tag support:** Replace entire biome categories at once - **Server-side:** No client installation needed (unless you want to use it in singleplayer, of course!) ### Experimental features These haven't been tested thoroughly yet, and can be changed or removed in future versions. They can potentially damage your world, so be careful! - **Full biome removal:** remove a biome completely instead of replacing it with another - **Chance based replacement:** Replace any percentage of a biome ## Caveats - **Works perfectly with:** Vanilla and datapack biomes (including Terralith) - **Terrain will NOT be changed:** Biome Replacer can't remove or create new rivers, oceans, mountains, etc. - **Cannot replace:** TerraBlender or Biolith biomes - you should use their native configs instead Note: Currently there is a bug with TerraBlender. If you install it and try to replace a _vanilla_ biome, it might sometimes still appear in the world. See [this issue](https://github.com/WerDei/Biome-Replacer/issues/21) for more information. (Oh, and if you are a developer knowledgeable in TB's workings, we'd appreciate the help on fixing this!) ## Setup 1. Install the mod, then run your client/server once to generate configuration file 2. Find `biome_replacer.properties` in the `config` folder 3. Add your replacement rules, then load up the world Tip: on client, you don't deed to restart the game every time you change your rules, you can simply leave and enter the world again. ### Configuration #### Basic replacement ``` minecraft:dark_forest > minecraft:cherry_grove ``` #### Tag-Based replacement Note: this does not work on 1.18.2 ``` #minecraft:is_forest > minecraft:desert ``` #### Options ``` ! Disable chat notifications muteChatInfo = true ```

Experimental features

Reminder: these aren't fully tested! Make sure everything works as it should before using these in a world you care about! #### Remove biome without replacement ``` minecraft:desert > null ``` #### Chance-based replacement ``` ! old_biome > new_biome [probability] ! For reference: 0.9 = 90%, 0.5 = 50%, 0.1 = 10%, etc. minecraft:taiga > minecraft:desert 0.5 #minecraft:is_mountain > minecraft:badlands 0.35 ```

## Examples ### Forest to Cherry Grove **Config:** ``` minecraft:dark_forest > minecraft:cherry_grove ```

### All Forests to Desert **Config:** ``` #minecraft:is_forest > minecraft:desert ```

### Adding mod compatibility **Config:** ``` terralith:lavender_forest > aurorasdeco:lavender_plains terralith:lavender_valley > aurorasdeco:lavender_plains ```

Lavender Forest replaced by Lavender Plains

### Removing unwanted biomes **Config:** ``` terralith:cave/infested_caves > minecraft:dripstone_caves ```

Infested Caves replaced by Dripstone Caves
