Chunk Randomizer
by eckelsoft
Chunk Randomizer makes each newly visited chunk of the world replace its blocks with a random block type, and it only starts after a command is run.
What it does
Once the randomization is started with the rc start command, every chunk a player enters gets re-rolled, so the terrain changes as the player explores. Blocks can be excluded from the shuffle with rc exclude add, and the mod is meant to avoid the lag that comes from chunks turning all at once. It runs on client and server and needs Fabric API. Files are published for Fabric only, for game versions 1.20.1 – 26.2, and the code is released under the MIT License as open source.
Key features
Randomized chunk visits
Each chunk a player visits gets new block types, so the world changes as it is explored.
Command-based start
Randomization begins only after rc start is run, and blocks can be kept out of it with rc exclude add.
Chunk Walker Boots
A pair of boots is added, and the world-randomization effects cost 10 durability per chunk.

Every chunk you visit is randomized to a new blocktype! Important: Run /rc start in chat to start the challenge. Chunk randomization only begins after this command.
