World Management & Pregeneration Tools

When a player walks into land nobody has visited, the server must generate it, and that cost lands while they are playing. On a busy server, a group exploring in different directions can drag the whole tick down.

Pregeneration moves the cost to a time you choose. A pregeneration plugin generates a region around spawn in advance, often with a world border, so players walking into it find terrain ready. Chunky does this and lets you pause and resume, which matters because a large area can take hours.

Multiple worlds let one server host a survival world, a creative plot world and a minigame arena at once. Multiverse-Core is the plugin for creating, loading and moving between worlds, with per-world settings.

Pregeneration uses disk space and takes real time, so plan the size: a larger radius means more storage and a longer wait. It also fixes the seed's terrain at the time you generate it, so do it once your world settings are final.

How large should I pregenerate? Match your world border. Generating far more than players will visit wastes disk and time.

Does Multiverse affect performance? Each loaded world has a cost. Load only the worlds you use and unload the rest.
