HexLands (Updated)

Terrain is divided into hexagons modeled on the Settlers of Catan board, and each hexagon contains a single biome. Neighboring hexes of different types meet at a border wall, so the boundaries between regions can be read at a glance on the map. The generator also stays compatible with worlds that use other biome-adding mods, handled automatically without extra setup.

The generator is configured through data packs. Its type string names the generator to use, the noise settings are chosen per dimension, and the biome source can be set to vanilla or to one of the known presets such as minecraft:overworld and minecraft:nether, written as a JSON object that follows the vanilla biome source format. The biome scale controls how many biomes are sampled to create hexes, with a default value, and higher values produce more random biome layouts. Worlds can also be created from World Presets, where a new preset using the hexlands:hexlands chunk generator is added with its own fields.

The mod runs on the server only, so players join without installing it. It is released under the MIT License and is open source, and its source code and issue tracker are public. Files are published for Fabric and NeoForge across 11 release versions, 1.21.6 – 26.3, with snapshot builds included. The mod was first published on 2025-08-05 and last updated on 2026-09-12.
