About this Mod
I made this small project because I find vanilla terrain boring, and many world generation mods have terrain that looks nice but isn't good for gameplay.
The datapack/mod doesn't add any new biomes, structures, or plants, but only improves various noise settings.
The terrain looks nice but is also well-suited for exploration and building.
All biomes, ores, and structures should still generate normally.
This datapack/mod also works well with biome mods.
I tested it with Nature's Spirit and everything worked without any issues.
Other biome mods should also work.
If you find any bugs or have suggestions for improvement, let me know!
