Hex Lands is a mod that is responsible for modifying the terrain generation of the game, to contain the biomes in demarcated terrain areas, as happens in many tabletop games. These plots will be hex shaped and each hex will contain a biome, although if two identical biomes appear side by side, the two hexes will merge.

This new generation of terrain will not be generated as soon as the mod is installed, but rather we will have to generate a new type of world. In the world customization options, in World Type, we will have to select the option: Hex Lands.
