How to pre-generate a world on a Minecraft Fabric server

The Chunky Pregenerator is a valuable mod for Minecraft Fabric that allows players to pre-generate chunks in their worlds. It helps optimize gameplay performance by generating chunks in advance, reducing lag and improving overall game stability. With Chunky, players can specify the size and shape of the pre-generated area, ensuring that their desired regions are fully loaded and ready for exploration or building projects.

The Fabric modloader must be installed. Learn how to here.
