Reworld (Fabric)
by NotRealGuest
Reworld is a Fabric world generation mod that lets a single world merge chunks generated from different seeds through a command.
What it does
A command named corrupt-world, with an optional seed argument, triggers the merging process in an existing world. Reworld is described as an experimental tool: it performs deep changes to chunk generation data, so the effect on a world can be strong. The mod only affects chunks that have not yet been generated, and it does not modify chunks already explored or built upon. Because of that, the author recommends creating a backup of the world before running the command, and the mod is intended for use in experimental environments at the user's own risk.
Reworld is server-side only, so only the server needs it, and players join without installing anything. It requires Fabric API. The mod's original command, reworld, is also available. Its in-game messages are available in Spanish only. Files are published for Fabric and 1.21.11 only, with 1.0.0 as the latest build, released under the CC0 1.0 Universal license, which is not open source.
Key features
Single-command corruption
The corrupt-world command merges different seeds within the same world, so new areas can mix terrain from several generators.
Chunk generation changes
Deep modifications to chunk generation data produce the merging effect, applied only to newly generated chunks.
Explored terrain untouched
Chunks that were already explored or built upon are not altered by the merging process.
Spanish in-game messages
Messages shown in the game interface are written in Spanish only.

How it compares
TextureCorruptor is a Fabric mod for 1.21.11 with a client-side only environment, released under the MIT License and open source, so it changes textures rather than chunk generation. World Corruptor is also server-side only and open source under the MIT License, but it targets 1.20.1 and is not published for 1.21.11. One Chunk Blocks is server-side only, covers 1.16.5 – 1.21.11 and is released under the MIT License, but it is not open source.
