How To Change The Galaxy Seed On Your Cubic Odyssey Server

The galaxy seed is the number your Cubic Odyssey galaxy is generated from. The default is 21945875634.

The seed is only used when your galaxy is created, so changing it means starting a new galaxy.

Danger

Starting a new galaxy deletes your current galaxy and everyone's progress in it. Create a backup first if you want to keep it.

Changing The Galaxy Seed

  1. 1
    Log in to Bropanel and Stop your server.
  2. 2
    In the sidebar, go to Files and delete the save_server folder.
  3. 3
    In the sidebar, go to Settings.
  4. 4
    Under Gameplay, edit Galaxy Seed (Read Info) and enter a number of up to 11 digits.
  5. 5
    Click Save & Restart to apply your changes.

Your server generates a new galaxy from the new seed when it starts. If you change Galaxy Seed (Read Info) without deleting save_server, your server keeps its current galaxy and seed, and says so in the console.
