Danger

This will delete or overwrite any progress you have made on the server.

Install Mods First

Before uploading your modded world, make sure to install all required mods on your server.

Finding Your Local tModLoader World Save File

1. Press Windows Key + R and enter this:

   %USERPROFILE%\Documents\My Games\Terraria\tModLoader\Worlds

2. Find both the .wld and .twld files for the world you want to upload.

   The .twld file contains your modded world data and is required.

For example:

• DirectorDocuments

  • DirectorMy_Games

    • DirectorTerraria

      • DirectortModLoader

        • DirectorWorlds

          • YourWorld.wld Your world save file
          • YourWorld.twld Modded world data

Steam Cloud Saves

If your world is stored on the Steam cloud, you need to temporarily move it off the cloud first:

1. Launch Terraria (tModLoader).
2. Go to the world selection menu.
3. Click the cloud icon next to your world to move it off the cloud. This will download a local copy of your save.
4. Re-enable Steam cloud after copying the files if desired.

Uploading Your tModLoader World to Your Server

1. Log in to the Game Host Bros Game Panel and Stop your Terraria server.
2. In the Game Panel, navigate to File Manager.
3. Navigate to the Worlds folder.
4. Upload both your .wld and .twld files.
   • DirectorWorlds

     • YourWorld.wld Your uploaded world save
     • YourWorld.twld Modded world data
5. In the Game Panel sidebar, navigate to Startup Parameters.
6. Set the World Name field to match your uploaded world file name.
7. Start your server.

Note

The World Name in Startup Parameters must match the name of your uploaded world files.

For example, if your files are MyWorld.wld and MyWorld.twld, set World Name to MyWorld.
