About this Mod
One Chunk Biomes turns world generation into a chunk-by-chunk biome mosaic.
Instead of large biome regions stretching across huge parts of the map, this mod assigns biomes at chunk scale. Every
chunk can become a different biome, which creates a chaotic patchwork world full of sharp biome borders, strange
transitions, and unusual survival routes.
This mod is meant for players who want a weird, experimental world generation style instead of normal biome layouts.
Notes
This mod changes biome generation for newly generated terrain. Existing chunks that were already generated before
installing the mod will not be changed.
