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).
• Chat Notifications: Optionally disable chat notifications for players when replacement rules are applied.
• Flexible Mod Compatibility: Works alongside biome libraries like TerraBlender and Biolith for seamless integration.

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

Note: While biomes added by libraries like TerraBlender or Biolith cannot be directly replaced, you can use Biome Replacer to adjust vanilla or datapack biomes to integrate modded ones.
