Datapack Chunk Pregenerator

Chunk Pregenerator, smoother Minecraft exploration

Chunk Pregenerator is a Java Edition data pack that generates selected chunks before players reach them. By preparing terrain in advance, it reduces the stutters and pauses commonly caused by on demand world generation during fast travel.

You can define a square area, choose its center, and set the desired radius in chunks, making it practical for planned exploration. It supports singleplayer and server side use across Minecraft Java versions from 1.21.5 to 1.21.11, as well as 26.1.x and 26.2. Larger areas require more time and resources, so sensible limits help protect performance. For a smoother Minecraft server experience, our BoxToPlay team recommends this useful optimization tool.
