Performant Random Chunk
By simonpacisUpdated 17 Oct 2026Mod
Turns every chunk you walk into into one random block type, so each part of the world looks totally different. Works in multiplayer too.
This addon changes the world as you explore it. When you enter a new chunk, almost every block in it becomes one single block type, picked at random. One chunk might be all stone, the next might be all sand or something odd. Air, water, lava and bedrock stay as they are, so the world still has caves, oceans and a bottom layer.
Changes are saved, so a chunk stays the same after you leave or the server restarts. Anything you build in a chunk after it changes is kept too. It works in multiplayer, including Realms and dedicated servers. The source says it is built to be light on the server and runs on mobile, console and more.
Features
- Each new chunk gets filled with one random block type
- Air, water, lava and bedrock are left alone
