Overview

When stepping into a chunk, a random block is chosen to replace every block in that chunk.

If you'd like to make a video or content using this pack, go for it! If you do so, you must provide credit to me (Ambiguous Chameleon) and provide a link to this pack in the description and/or comments. Thank you!

Additions

  • Updated for Minecraft 26.1 - 26.2
  • Added a blacklist feature, allowing players to select blocks they don't want chunks to generate as
  • Added new /trigger cheats
    • /trigger ac.random_chunk.blacklist (opens a blacklist menu, to toggle which blocks are allowed to spawn as chunks)
    • /trigger ac.random_chunk.blacklist.clear (clears the blacklist)
    • /trigger ac.random_chunk.blacklist.presets (opens a menu to blacklist large groups of blocks all at once)
    • /trigger ac.random_chunk.reroll (rerolls the chunk you are standing in to use a new random block)
  • Added 2 blacklist presets (more to come as I think of them / they are suggested)
    • Leaves, which can generate a lot of lag as they decay
    • Partial Blocks, which can be easy to fall through and die to fall damage

Changes

  • Nether portal blocks now won't get destroyed when a chunk changes its block
  • Removed iron chain as a spawnable block, due to a Forge modloader error
  • Light optimizations
