The Complete Guide to Multiverse-Core: Creating, Importing, and Managing Worlds

Multiverse-Core is the essential multi-world management plugin for Minecraft servers. It allows you to run multiple separate worlds—such as a Survival world, a Creative plot world, a Nether dimension, and custom minigame maps—on a single Spigot or Paper server instance.

This complete guide covers installing Multiverse-Core, creating new worlds, importing existing custom maps, teleporting between worlds, and configuring per-world rules.

Step 1: Install Multiverse-Core via the Cubes Panel

Log in to your Cubes Hosting Game Panel and select your Minecraft server.
Go to Tools > Plugin & Mod Installer on the left menu.
Search for Multiverse-Core (and optional add-ons like Multiverse-Inventories for separate inventories or Multiverse-Portals for portal links).
Click Install and restart your server from the Console.

Step 2: Creating New Worlds from Scratch

Multiverse allows you to generate new worlds with different environment types and world generators.

Create a Standard Survival World:
```
/mv create survival_world normal
```
Create a Superflat World (for Creative / Testing):
```
/mv create creative_world normal -t flat
```

Create a Custom Nether or End Dimension:

/mv create custom_nether nether
/mv create custom_end end

Step 3: Importing Existing Custom Worlds

If you downloaded a custom adventure map, a spawn build, or backed up a single-player world, you can import it into Multiverse in three steps:

1. Upload the World Folder

Open your Game Panel File Manager (or connect via SFTP).
Upload your custom world folder directly into your server's root directory (the main folder alongside your server.properties file).
Ensure the folder name contains no spaces or special characters (e.g. rename My World to my_world).

2. Run the Import Command

Connect to your server in-game as an Operator (OP) or use the Game Panel Console.
Run the import command, specifying the folder name and world environment (normal, nether, or end):
```
/mv import my_world normal
```
Multiverse will scan the folder, load the level data, and display a confirmation message: Complete!.

Step 4: Teleporting & World Management Commands

Once your worlds are created or imported, use these commands to navigate and manage them:

Action	Command	Description
List All Worlds	`/mv list`	Shows all currently loaded and unloaded worlds.
Teleport to a World	`/mv tp <worldname>`	Instantly teleports you to specified world's spawn.
Set World Spawn	`/mv setspawn`	Sets the spawn point for your current location.
Unload a World	`/mv unload <worldname>`	Unloads a world from RAM to free up server resources.
Load a World	`/mv load <worldname>`	Reloads a previously unloaded world back into memory.
Remove a World	`/mv remove <worldname>`	Unregisters a world from Multiverse without deleting files.
Delete a World	`/mv delete <worldname>`	Permanently deletes a world and wipes its files.

Step 5: Configuring Per-World Rules (`/mv modify`)

Multiverse allows you to customize game rules, PvP, mob spawning, and game modes individually for each world without affecting the rest of your server.

1. Changing World Game Modes

Force a world into Creative mode: /mv modify set gamemode creative
Force a world into Survival mode: /mv modify set gamemode survival

2. Toggling PvP & Mob Spawning

Disable PvP combat in spawn/creative worlds: /mv modify set pvp false
Disable hostile mob spawning: /mv modify set monsters false
Disable passive animal spawning: /mv modify set animals false

3. Setting World Aliases & Colors

You can change how a world's name displays in chat or tab lists:

/mv modify set alias &a&lCreative_Plots

Useful Add-ons for Multiverse

To take full advantage of multi-world setups, consider installing these official Multiverse add-ons via Tools > Plugin Installer:

Multiverse-Inventories: Keeps player inventories, health, and ender chests separate between worlds (e.g. players won't keep creative items when switching to survival).
Multiverse-Portals: Create custom in-game obsidian/water portals that teleport players between worlds when walked through.

Conclusion

Multiverse-Core turns your single Minecraft server into a multi-world network. Whether you create fresh flat worlds, import custom adventure maps, or configure peaceful lobby zones with /mv modify, Multiverse gives you complete control over your server's dimensions!
