Chunky Offline

by lullaby

Chunky Offline lets a server owner pre-generate chunks for a world without any player online, using the Chunky engine it requires.

What it does

Chunky Offline runs its generation task automatically once a process is started, so the server keeps working when nobody is connected. A run uses default values of a 10000 block radius around the centre at 0 0, and the command to start it can be issued from the console. The mod is published for Fabric, Forge, NeoForge and Quilt across 1.21 – 26.3 and needs the Chunky mod installed alongside it. Only the server needs it, since players may leave it out.

Key features

  1. Offline pre-generation

    Chunks are generated while no player is online, so the server can prepare a world in advance.

  2. Global message control

    Server messages about the generation progress can be turned on or off.

  3. Force start and cancel

    A process that was canceled can be restarted by hand, with a forced start option.
