Chunky (Forge/NeoForge)

The Chunky mod provides a powerful tool for pre-generating chunks in Minecraft, allowing you to create game worlds in advance for smooth gameplay without delays.

Main Features

With this mod, you can run multiple chunk generation tasks simultaneously, which is especially useful for maximizing processor power. All processes can be paused and resumed at any time, preserving achieved progress. During operation, detailed statistics are displayed: number of processed chunks, completion percentage, remaining time, and processing speed.

The mod supports various world generation shapes and is compatible with world borders when the additional ChunkyBorder addon is installed.

Access Requirements

To use the mod, you must be an operator on the server (for this, an administrator must execute the command op <username> in the console) or play in single-player mode. In some older versions, enabling cheats through world settings or the "Open to LAN" function may be required.
