Nebula Pre-generator

A simple mod that pre-generates world data at world creation. Useful in Modpacks with pre-build dimensions or areas.

Works by copying “world data presets” (region/entities/poi files) for the overworld or for any custom dimension from a config folder into a world’s save folder, mirroring the exact same relative path. This lets a developer ship pre-built terrain (custom dimensions, farms, spawn regions, entities etc.) that appears already generated the first time a player joins a brand-new world.

This mod is intended for Modpack developers, by it’s own, it does nothing.
