How to pause, resume or cancel a pregeneration task

Pregeneration can run for a long time, and sometimes you need your server or game back. The /pregen command lets you interrupt it without losing everything.

Pause and resume

1. Type /pregen pause to stop the current run. Chunks that are already generated stay in the world.

2. Use /pregen start later to continue the queued work.

3. Press Tab after /pregen to see the exact subcommands your install offers.

Remove queued tasks

1. If you queued the wrong radius, dimension or centre, pause first.

2. Use /pregen clear to empty the queue.

3. Queue the correct task again with /pregen gen, then start it.

Good to know

• Closing the world or server normally while a task is running is safer than killing the process. A forced kill can interrupt chunk saving.
• Chunks that were already generated aren't harmed if you queue an overlapping area later. The mod simply has less new work to do in that region.
• Queue tasks one at a time and check them before starting if you're unsure about coordinates.
