Biome Replacer

by werdei

With Biome Replacer, a server owner swaps or removes unwanted biomes by writing plain rules in a properties file, without editing datapacks.

FabricForgeNeoForgeQuiltServer-side onlyMIT LicenseOpen source1.18.2 – 26.3

What it does

Each line of the rules file pairs an existing biome with the biome that should replace it. Biome tags can stand in for single biomes, and a dedicated keyword deletes a biome from generation entirely, for example to strip Terralith's skylands from a world. Bracketed dimension IDs limit a rule set to one dimension, which matters only when custom dimensions generate the same biomes.

The mod changes biome placement, not terrain shape, so oceans cannot become land and ocean-only worlds cannot be made. Only the biome libraries it supports can be changed, which leaves out biomes added by other generation frameworks. Fabric API is required on every loader, and the server runs the mod alone, so players join without installing anything. The mod is open source under the MIT License and published for 1.18.2 – 26.3 across Fabric, Forge, NeoForge and Quilt.

Key features

  1. Single properties file

    Replacement rules are written in a single biome_replacer.properties file in the config folder.

  2. Biome tag targeting

    Rules can target whole biome tags, not only individual biome IDs.

  3. Biome removal

    A dedicated keyword removes a biome from generation entirely.

  4. Dimension headers

    A bracketed dimension ID limits the following rules to that dimension.

  5. Runs at world start

    Rules are applied once when the world loads, so generation speed is not affected.

Questions

Does Biome Replacer need Fabric API?

Yes. Fabric API is listed as a required dependency, so it must be installed alongside the mod.

Must Biome Replacer be installed on the client?

No. It runs on the server alone, so players need nothing extra to join. Clients need it only when playing in single-player.

Can Biome Replacer change biomes from every generation framework?

No. It works only with the biome libraries it supports, so biomes added through other frameworks are outside its reach.

Do changes need a restart?

On a client, leaving and re-entering the world applies new rules without restarting the game.

What the author says

Biome Replacer is a simple and easy-to-use utility mod for removing unwanted biomes \*Please note that Biome Replacer cannot change terrain shape. This means that it's impossible to change oceans to land, create ocean-only worlds, etc.
