Chunky Mod is designed for pre-generating chunks in the Minecraft game world. In some cases, this can reduce the load on a computer or server, which is particularly useful for servers or when using many mods that affect chunk generation. When moving through the world, the game simultaneously generates new chunks and renders them for the player. After installing many mods, you may notice that new chunks generate more slowly, but if you travel through areas you’ve already visited, the game runs reasonably well. This is because the chunk generation process itself places a significant load on the CPU. If you have many mods installed, especially if they are poorly optimized, the CPU load increases. This mod allows you to pre-generate a specific area around you, so you can later move through it without the game needing to generate that terrain. The mod itself won’t pre-generate anything automatically, but you can activate it with specific commands and then wait for the process to complete (during which your processor will be fully utilized).

Features:

  • Allows players to generate chunks in advance to optimize performance.
  • Users can start, pause, resume, or cancel chunk generation tasks.
  • Supports generating chunks in various shapes like squares, circles, or custom patterns.
  • Displays progress in percentage, estimated time remaining, and chunks processed.
  • Enables multiple chunk generation tasks to run simultaneously for better CPU utilization.
  • Works with ChunkyBorder to respect world borders.
  • Shows chunks processed, completion percentage, estimated time, and processing rate.

Commands:

  • /chunky start – Starts a new chunk generation task
  • /chunky pause – Pauses the current chunk generation tasks, and saves progress
  • /chunky continue – Continues running current or saved chunk generation tasks
