Not Just Biomes is a Fabric only mod that aims to alter and improve worldgen in a slightly different fashion than other worldgen mods. Instead of going far over the top and overloading the game with dozens new structures and biomes, this mod aims to introduce meaningful changes to the vanilla biomes and structures while keeping it like vanilla, in both style and simplicity.
Adventure through the revamped Taiga, Forest, and Birch Forest biomes, which now have fallen trees, natural clearings and more. Lurk around in the Swamp and Mangrove Swamp biomes where there's now pools of mud and more flowers.
Delve deep underground and find one of the several variants of the revamped dungeon, with new loot and decorations to discover in them. Venture into a Dark Forest, where you may find the rejuvenated Woodland Mansion with some more horrors and loot.
