About this video: Pregenerating your Minecraft world is one of the best ways to reduce lag caused by players exploring and generating new chunks. In this video, we show you how to install and use Chunky in both single-player worlds and Minecraft servers. Chunky supports Fabric, Forge, NeoForge, Bukkit, Folia, and Paper, so the process works with nearly any Minecraft setup.
First things first, you will need to download the correct version of Chunky for the platform you are running. If you have a Fabric, Forge, or NeoForge installation, add Chunky to your mods folder. Fabric users will also need the Fabric API installed. For Paper and other plugin-based servers, place the Chunky file in your plugins folder instead. You can then launch Minecraft or restart your server.
Before generating chunks, we recommend setting a world border. Stand where you want the center of your world to be and run “/worldborder center ~ ~”. From there, use “/worldborder set” followed by the total size of the world border. For example, setting the world border to 2500 creates an area extending approximately 1250 blocks in each direction from the center.
Once your world border is ready, run “/chunky worldborder” to configure Chunky to generate everything inside it. If you do not want to use a world border, you can set the generation area manually using “/chunky center” followed by “/chunky radius” and your desired radius. After that, enter “/chunky start” to begin pregenerating the world.
You can check the current status at any time with “/chunky progress”. On a server, progress information will also appear in the console. You will need to be an operator to run these commands on a server, while cheats must be enabled in a single-player world.
Chunky can also pregenerate the Nether and End. Use “/chunky world minecraft:the_nether” to select the Nether, set its radius, and start another generation task. Pregenerating the Nether is especially useful because players can quickly create new chunks while traveling through it.
If you need to temporarily pause generation, use “/chunky pause”. You can completely stop the tasks with “/chunky cancel” followed by “/chunky confirm”. Chunky can also resume its work after a crash or restart, so you will not need to begin the entire process again.
With that, you now know how to pregenerate a Minecraft world using Chunky. If you have any questions, let us know in the comments. Otherwise, give the video a thumbs up and subscribe to the channel if you haven’t already. It really helps us out, and it means a ton to me. Thanks in advance!
