Chaotic World
Chaotic World changes world generation settings such as the lowest build limit, the sea level and biome scale, so terrain and structures can differ from vanilla.
What it does
The mod exposes world generation options in its configuration, including the lowest generating height, which lets structures such as Trial Chambers still generate below bedrock, the sea level and the scale of biomes. Its settings are named and searchable in the config screen, and the author plans to add more of them later. Because it changes the generator itself, the result is a world that can look very different from the default one.
The mod is aimed at players who want to experiment with generation settings in a single world or on a server. It is compatible with the fast world generation mod C2M, and it does not change the surface beyond what its settings control. A data pack version also exists, which the author links for a final-moments world, and the mod depends on the Nobie Link library.
Files are published for Fabric, Forge, NeoForge and Quilt, plus a data pack, across six release versions 1.21.7 – 26.2, under the MIT License, which is not open source. The server must run the mod, while players may leave it out and still join.

I made this mod just for fun while experimenting with the world genertion settings. What this mod do is 3 things: - Changing the lowest limit for generating the world to 0 (_structures such as Trial Chambers still generate under bedrock_). Spoiler
