How do I generate a new world, or upload my own instead? — Control Panel

Q: How do I set a new seed?

Set level-seed in server.properties before generating the fresh world.

Q: My uploaded world is being ignored — why?

Almost always a name mismatch between your folder and level-name. Match them and restart.

You've got two easy paths: let the server create a fresh world for you, or supply your own. Both come down to a stop, a file change, and a restart.

Generate fresh vs. upload your own

To generate a fresh world, you remove (or rename) the current world folder and let the server rebuild it on start — optionally with a new seed. To upload your own, you drop your world folder into the server root and make sure its name matches your configured world name. In both cases, the server reads server.properties to decide what to load.

How to do it

To generate a fresh world: stop the server, delete (or rename) the current world folder in Files, set a new seed in server.properties if you like, and start — it builds a new world.
To upload your own: place your world folder in the server root so its name matches level-name, then restart.

Warning: Back up before deleting a world — deletion is permanent without a copy. Download the folder via Files or SFTP first if there's any chance you'll want it back.

Tips & best practices

Keep the uploaded world's folder name identical to your config's world name (level-name), or the server will ignore it and generate a new one instead.
