A Hytale save keeps both world and player data (inventories and progress) in its universe folder. To bring your singleplayer characters to a FREAKHOSTING Hytale server, back up the server, stop it and replace Server/universe with your singleplayer universe folder over SFTP. Then check that "World" under "Defaults" in Server/config.json matches a folder in Server/universe/worlds and start the server.

​
Before you start

  • Your server must be logged in to a Hytale account once and have started. If it never has, see getting started.
  • Find your singleplayer save on your PC. You need its universe folder.
  • Install an SFTP client such as FileZilla or WinSCP. See connect via SFTP.
  • Your game and the server should be on the same Hytale version.

​
World only, or world and players?

Replacing Server/universe replaces every world and all player data on the server. Make a backup first, so you can restore the old universe if you need it.

​
How to import your universe with player data

1

Back up the server

Open Backups and make a backup. See backups.
2

Stop the server

Stop the server and wait until it shows as offline. Hytale writes its save data while it runs.
3

Connect over SFTP

Use the SERVER ADDRESS and USERNAME from the SFTP card on Settings, with your Game Panel password.
4

Rename the old universe

On the server, open the Server folder and rename universe to universe-old. You can delete it later, once everything works.
5

Upload your universe

Copy your singleplayer universe folder into the Server folder, next to config.json.
6

Check the default world

Look in Server/universe/worlds/ for the world folder names. Open Server/config.json in Files and make sure "World" under "Defaults" is one of them. If you change it, click Save Content.
7

Start and test

Start the server and join. Your character and inventory should be as you left them.

​
What if my character is missing?

To go back, stop the server, delete the new Server/universe, rename Server/universe-old to universe and start again. Or restore your backup.

​
Frequently asked questions

​
Can I add only my character to an existing server world?

Player data is stored in the universe together with the worlds. The safe way is to move the whole universe. If you need something more specific, open a ticket.

​
What happens to the players who were on the server before?

Their data was in the old universe. It is still in Server/universe-old and in your backup, but they start fresh in the new universe.

​
Can I upload with the File Manager?

A universe is a folder with many files, so SFTP is faster and keeps the folder structure intact.

​
Will this change my server settings?

No. config.json, permissions.json and the other files in the Server folder stay as they are. Only the world settings inside Server/universe/worlds/ come from your save.
