Biome Replacer (Neoforge)

Fabric Version

Description

Biome Replacer is a small, server-side mod that allows you to replace one biome with another without affecting other aspects of world generation. This versatile tool is perfect for:

• Preventing specific datapack biomes from generating
• Ensuring modded biomes appear correctly
• Fine-tuning an almost-perfect seed

Key Features

• Direct Biome Replacement: Easily swap one biome for another using straightforward rules.
• Biome Tag Replacement: Replace entire groups of biomes at once using biome tags (e.g., #minecraft:is_forest).

Mod Compaibility

Note that this mod is intended mostly for replacing vanilla and datapack biomes. Biomes added using libraries like TerraBlender or Biolith cannot be replaced; you should use the mod's config to tweak or remove them instead. That said, this mod can safely be used alongside these libraries, and it's even possible to replace vanilla/datapack biomes with modded ones.

Configuration

Setting up Biome Replacer is straightforward:

1. Locate the biome_replacer_forge.properties file in your config folder.
2. Add replacement rules using the following formats:
   • Direct Replacement:

     old_biome > new_biome
     

   • Tag-Based Replacement:

     #tag > new_biome
     

3. Optional: Disable chat notifications by setting:

muteChatInfo = true
