Chunky Mod builds the chunks of your world ahead of time, so the game does not have to make fresh terrain while you walk through it. Chunk generation is one of the heaviest jobs a Minecraft client or server does, and it gets slower once a lot of mods hook into it.

Frequently asked questions

How do I start pre-generating chunks with chunky?
Run the chunky command to open its interface, then use the start subcommand with a shape and radius (or a center point) to kick off the task. Nothing generates until you explicitly start it, so the mod sits idle until you issue that command.
What command do I use to pregen chunks around my base?
Stand where you want the center, then run the chunky start command with a radius and shape so the area is centered on you. You can also specify explicit coordinates instead of relying on your current position.
How do I pick the radius and shape for a chunky task?
Use the shape option to choose between a square and a circle, and the radius option to set how far out from the center it generates. A circle covers less area for the same radius but avoids generating corners you may never visit.
Can I run more than one chunky task at the same time?
Yes, you can start multiple tasks and they run concurrently, which spreads the work across more of your CPU. Running several at once speeds up total throughput but each individual task finishes slower than if it ran alone.
