Multiverse-Core: Managing Multiple Worlds

Multiverse-Core allows you to run multiple independent Minecraft dimensions (e.g. an SMP survival world, a creative plot world, a flat build world, and a resource gathering world) simultaneously on one server instance.

Installation

1. Download Multiverse-Core.jar from SpigotMC or [Hangar].
2. Upload the .jar to your plugins/ directory.
3. Restart your server.

Creating New Worlds

Run these commands in console or in-game:

1. Create a Standard Normal World

/mv create survival_resource NORMAL

2. Create a Flat World (Great for Creative Building)

/mv create creative_plots NORMAL -t FLAT

3. Create a Nether or End World

/mv create custom_nether NETHER
/mv create custom_the_end THE_END

Teleporting Between Worlds

# Teleport yourself to another world
/mv tp world_name

# Teleport another player
/mv tp PlayerName world_name

# Set the world spawn point
/mv setspawn

Importing Existing Worlds

If you uploaded a custom map folder (e.g. AdventureMap) to your server root directory:

/mv import AdventureMap NORMAL

Managing Memory with Multiple Worlds

On 4GB RAM servers, each loaded world maintains its own spawn chunk memory. To keep performance optimal:

1. Open plugins/Multiverse-Core/worlds.yml.
2. Locate worlds that players visit infrequently (like a mining world).
3. Set:

keepSpawnInMemory: 'false'

1. This ensures chunks unload when no players are in that dimension, keeping RAM free for active players.
