World of Chaotic Blocks

Creating a world with the World of Chaotic Blocks type replaces normal terrain with blocks placed about 10 blocks apart along the X, Y and Z axes, so the result looks like a strange floating world. Block choices are drawn from the loaded block registry, so vanilla blocks and blocks from any other installed mod can show up in the world. Because of that, the final generation depends on the modpack, and the same settings can give a very different world on another install.

The world type is meant for survival challenge runs. Useful resources appear close together but can sit in dangerous spots, and rare blocks float above or beside empty space, so players have to explore, improvise bridges across gaps and rely partly on luck when planning a route. The Nether and End stay mostly normal, so progression is still possible while the Overworld changes completely. Some unsafe technical blocks, such as air, portals, command blocks and structure blocks, are excluded from generation, along with blocks that closely resemble vanilla ones.

The mod is published for Forge 1.20.1 only. It runs on the server side alone, so players join without installing it, and it is released under the MIT License, which is not an open source license. Setup needs Minecraft Forge 1.20.1: drop the mod file into the mods folder, open the world settings and choose the World Chaotic Blocks option before generating a new world.
