Mod Chunky

Chunky, the chunk pregeneration mod

Chunky is a utility mod for Fabric, Forge and NeoForge that pre generates chunks in your Minecraft world so terrain is calculated in advance instead of during exploration. By offloading world generation beforehand, it helps your Minecraft server stay smooth, especially with heavy worldgen mods or large maps.

The mod lets you define shapes such as squares or circles, track progress and estimated time, and run multiple tasks while monitoring CPU usage. It works both in singleplayer and on any dedicated serveur Minecraft or servidor Minecraft where you want stable performance, which is why at BoxToPlay we particularly recommend it for demanding survival or exploration focused worlds.
