How To Pre-Generate Your World using Chunky?

Minecraft's world creation relies on various calculations and is generated dynamically as the world is explored, meaning it is not pre-generated when gameplay begins, but instead generates as you play.

Pre-generating the world and setting up a world border can significantly boost your server's performance and removes chunk lag entirely while still allowing to have a massive world for yourself, friends and/or community.

How do I pre-generate my world?

For this tutorial, we'll be using the Chunky plugin on my PaperSpigot server.

• Bukkit/Spigot/Paper: https://www.spigotmc.org/resources/chunky.81534/
• Fabric/Forge/Sponge: https://modrinth.com/plugin/chunky/versions

1. Head over to the Game Panel and stop your server.
2. Download the Chunky plugin and upload it to your plugins folder.

3. Start the server and make sure the plugin is GREEN on the ‘/plugins’ list. If it's red, make sure you've installed the version which is compatible with your server.

4. Join the server and run the following commands. Edit them to your liking.

chunky center 0 0       - This makes the worldborder to be around the center of the world (x 0 z 0).
chunky radius 10000     - This makes the worldborder 10,000 blocks away from the center.
chunky start            - This starts the pre-generation progress.

Once you've ran the commands, you can see the pre-generation process in the server's console.

It is completely normal for the pre-generation to take a few hours. The length depends on how big you'd like the world to be. It is recommended to start the generation when you’re asleep and let it generate the chunks overnight.
