Unbiased Worldgen

by GFBruno

Unbiased Worldgen changes how biomes are distributed across the overworld, so warm, cold, humid and arid biomes appear more evenly.

What it does

The mod alters the temperature and humidity noises that decide where each biome generates. Biomes that were rare under the default noise, such as warm, cold, humid and arid ones, turn up more often, and the overworld gets a more balanced mix. It is a server-side change: the server must run it, while players can join without installing anything. Unbiased Worldgen is published for Fabric, Forge, NeoForge and Quilt, and as a data pack, with builds for 1.21, 1.21.1 and 26.2 and 1.0+mod for 26.2 as the latest file. The mod is released under the MIT License and is not open source.

Key features

  1. Balanced biome spread

    Warm, cold, humid and arid biomes generate more often, reducing long stretches of the same climate.

  2. Adjusted temperature and humidity

    The temperature and humidity noises that place biomes are reshaped, so the overworld is distributed more evenly.

  3. Custom biome compatibility

    Custom biomes that do not alter temperature or humidity keep working alongside the changed distribution.

Questions

Does Unbiased Worldgen need to be installed on clients?

No. Only the server has to run the mod; a player can join a server that runs it without installing anything, so the mod works on the server alone.

What the author says

This mod/datapack changes the temperature and humidity noises so biomes can be more evenly distributed across the overworld, so finding the biome you want isn't as bad this should be compatible with custom biomes as long they don't change temperature and/or humidity
