FabricClient required, server optionalCreative Commons Attribution Non Commercial No Derivatives 4.01.21.1

What it does

Chunks are assigned biomes in a pattern that changes the look of the terrain as the player moves through the world. Two world types are offered: a line type that stretches the mix along one axis, and a square type that spreads it across a grid of chunks. The mix is meant as a playful challenge, and strange things happen as biome borders cross the landscape. Files are for Fabric only, at version 1.21.1.

Key features

  1. New biome mix

    Each chunk takes a biome from a mixed set, so neighboring areas can look very different.

  2. Two world types

    A line type and a square type arrange the chunk pattern in different shapes.

  3. Challenge-style play

    The mod is built around the odd results of mixed chunks, turning exploration into a challenge.
