Description

square-biomes is a Fabric mod for Minecraft 1.21.11 that replaces natural biome borders with a strict square grid.

Logo

Each biome is resolved per square cell, producing a clean tiled overworld instead of vanilla's curved climate-driven layout. The mod also supports strong randomization, so overworld biome distribution can be much less dependent on vanilla climate rules.

Features

  • Square biome borders
  • Configurable biome square size
  • Configurable cell jitter
  • Configurable random biome chance
  • Random biome mode applies only to the overworld
  • Nether and End are excluded from random biome selection
  • Uniform random selection across unique overworld biomes

Default config

  • gridSizeBlocks: 128
  • cellJitter: 0.85
  • randomBiomeChance: 0.8

Requirements

  • Minecraft 1.21.11
  • Fabric Loader
  • Fabric API
  • Java 21

Important

  • New worlds are recommended
  • Existing worlds can show visible borders where new chunks generate
