This datapack/mod adjusts the scale of biome noises by about 2x in order to shrink biomes in the world. I can't guarantee compatibility with other worldgen packs and mods. It looks fine with only vanilla but it will almost definitely look goofy with certain biome mods that add many biomes. Probably incompatible with Terralith.
