Rexle's better Overworld
by Rexle25
Rexle's better Overworld changes the noise settings that shape vanilla terrain, without adding new biomes, structures or plants.
What it does
The project was made because vanilla terrain can look plain next to many world generation mods. This datapack and mod keeps the existing biomes, ores and structures and generates them as usual, while reshaping the terrain through tuned noise settings. The result is intended to look better for exploration and building, though the author notes that nicer terrain does not by itself make gameplay better.
Because it only adjusts noise parameters, it fits alongside biome mods. The author tested it with Nature's Spirit and reports no issues, and says other biome mods work as well. Bugs, suggestions and improvement ideas are welcome through the issue tracker.
The mod is published for Forge and NeoForge across 14 release versions, 1.20.1 – 1.21.7, and a data pack build is also available. The server must run it, while players may leave it out. It is released under the MIT License and is not open source.
Key features
Tuned terrain noise
Changes the noise settings that drive vanilla terrain shape, so hills and valleys differ from default generation.
Vanilla content kept
Biomes, ores and structures still generate normally, with no new content added.
Biome mod compatibility
Works alongside other biome mods; the author confirmed this with Nature's Spirit.
Data pack option
A data pack build covers servers that prefer not to install a Forge or NeoForge mod.

What the author says
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…
