As players dive deeper into Hytale, many eventually want to turn their singleplayer adventures into shared multiplayer experiences. Whether you are preparing for cooperative play during Hytale early access or planning a long-term community world, transferring your single-player save to a multiplayer server is a crucial step.

This guide explains how to move your world to either a self-hosted server or a hosted multiplayer Hytale server, while preserving your builds, player data, and mods.

How Hytale Stores World Data

Hytale organizes world data in a way that makes transfers relatively simple once you know where to look.

Each world folder contains:

  • universe folder – stores world terrain, structures, and player data
  • mods folder – contains all installed mod .jar files, if used

The universe folder is required for any transfer. If mods were enabled in singleplayer, those must also be copied to the multiplayer server.

Transferring A Singleplayer World To A Self-Hosted Hytale Server

Self-hosting gives you full control over your Hytale server, but requires manual file management.

Step 1: Locate Your Local Hytale Save Directory

To find your singleplayer world files on Windows:

  1. Click the Windows icon
  2. Search for and open Run
  3. Paste the following path:

%AppData%\Hytale\UserData\Saves

  1. Press Enter

This opens the Hytale saves directory. Open the folder that matches the world you want to transfer.

Inside, you will find the universe folder and a mods folder.

Step 2: Prepare Your Self-Hosted Server

  1. Stop your Hytale server completely
  2. Open the server root directory
  3. Locate the existing universe folder
  4. Rename it to something like:

universe-old

This ensures the server does not load the default world.

Step 3: Copy The Universe Folder

Copy the entire universe folder from your single-player world and paste it directly into the server root directory.

Make sure:

  • The folder name is exactly universe (rename the old folder if needed or delete the old)
  • No files are missing or partially copied

Step 4: Transfer Mods (If Used)

If your singleplayer world used mods:

  1. Open the mods folder inside your singleplayer world directory
  2. Select all mod .jar files
  3. Copy them into the server’s mods folder

Using mismatched mods is one of the most common causes of server crashes.

Step 5: Start The Server

Once the files are in place:

  • Start your server
  • Join the world
  • Confirm that builds, terrain, and player inventories are intact

Transferring A Singleplayer World To A Hosted Multiplayer Hytale Server

Using a managed host simplifies the process significantly, especially for players new to multiplayer Hytale hosting.

Step 1: Ensure Your Server Is Offline

  1. Head over to console and turn off the server by click on "Stop".
  2. (Optional) Create a backup by going to "Backups" tab you can rollback incase something goes wrong.

Step 2: Rename The Existing Universe Folder

  1. Find the current universe folder on the server by going to your "Files" tab
  2. Rename it to:

universe-old

This prevents the server from loading the default world data.

Step 3: Find Your Singleplayer Save Files

Locate your local world files:

  1. Open Run from the Windows Start menu
  2. Enter:

%AppData%\Hytale\UserData\Saves

  1. Press Enter

Open the folder for your desired world and keep it ready for upload.

Step 4: Connect To Your Server Via SFTP

In your server panel, head over to the "Settings" tab and click on "Launch SFTP"
to allow access from your FTP client (such as WinSCP) to your hosted server and log in using the credentials from your hosting panel.

When logged in you will have access to the server root directory.

Step 5: Upload Your Universe Folder

From your local machine:

  • Drag and drop the entire universe folder into the server root via SFTP
  • Ensure the folder name remains unchanged

Step 5: Upload Mods (If Used)

If mods were enabled in singleplayer:

  1. Open the mods folder inside your world folder on your pc
  2. Select and copy all mods and .jar files
  3. Upload them into the server’s mods folder via SFTP by dragging them in

Step 6: Start The Server

Once uploads finish:

  • Start the server from the hosting panel by going to "Console" tab
  • Join the game and verify that everything loads correctly

Your singleplayer world is now live as a multiplayer Hytale server.

Common Issues To Watch For

  • Server Fails To Start
    Usually caused by missing or incompatible mods.
  • World Loads But Player Data Is Missing
    The full universe folder may not have been copied.
  • World Resets To Default
    The old universe folder was not renamed properly.
  • Slow Uploads
    Large worlds can take time over SFTP. Let transfers finish before starting the server.
