Random Chunk 

Every chunk. One block type

 

Random Chunk is a lightweight Java datapack that transforms your world into an unpredictable patchwork of single-block type chunks. Every time you step into an unvisited chunk, it gets filled — floor to ceiling — with a randomly chosen block type. No two worlds will ever look the same.

Features

- 10 block categories rolled per chunk: Stone, Wood, Wool, Concrete, Terracotta, Metal, Nether, End, Miscellaneous, and Special blocks

- Fully automatic — no commands needed after installation

- Chunk-based detection: only triggers on newly entered chunks

- Lightweight — minimal performance impact (maybe) 

Installation

 

1. Download `Chaos_Chunk_v5.zip`

2. Place it in your world's `datapacks/` folder

3. Run `/reload` in-game

4. Start exploring 

 

 Compatibility

| Version | Support |

| Java 1.21.9 – 1.26.1 | ✅ Fully supported |

⚠️ Disclaimer

  • This datapack permanently modifies chunks as you explore — use a fresh world for best experience
  • Not responsible for corruption on existing worlds with important builds
  • Underground terrain is also overwritten
  • Always backup your world before installing
