World Pregen

by redemoles

World Pregen generates map chunks ahead of players, so terrain is already made before anyone walks there, through a datapack that sets the area and dimensions.

What it does

Pre-generation fills chunks in advance so that players do not wait for terrain to form as they explore. The mod is delivered as a datapack and targets the overworld, the nether and the end, each with its own dimension setting. Server owners choose the size of the area, with options from 2k up to 20k, and the bounds can be set at 1000 and -1000. Files are published for Fabric, Forge, NeoForge and Quilt for 26.3, with the 1.21.9 – 26.3 range listed. The server must run it, while clients may leave it out. Released under the MIT License; the source code and issue tracker are public.
