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

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:

Documents

My_Games

Terraria

tModLoader

Worlds

YourWorld.wldYour world save file

YourWorld.twldModded 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.

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.
Worlds
YourWorld.wldYour uploaded world save
YourWorld.twldModded 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.
