Mod Biome Replacer

Biome Replacer

Biome Replacer is a Java Edition utility mod that lets you remove unwanted biomes or replace them with alternatives through a simple configuration file. It is especially useful for refining datapack based world generators such as Terralith, and can also help adjust biomes added by compatible mods. Rules may target individual biomes, tags, or specific dimensions, while a null value completely removes a biome from generation. The mod runs server side, works with Fabric, Forge, NeoForge, and Quilt, and has negligible performance impact because it acts when the world starts. It changes biome selection, not terrain shape, so test configurations carefully on your Minecraft server with BoxToPlay.
