Terraria tConfig Modding - Tutorial 1 - Setting Up-0

Requirements Edit

tConfig is very easy to set up, but you must follow the directions carefully, otherwise some things may not work.

  • You will need a legitimate copy of the game purchased through Steam.
  • You will need administrative privileges on your computer.
  • You will need to install a copy of the Terraria Game Launcher. (See Below)

Installing tConfig Edit

Please note: Most antivirus software will report tConfig as a potential threat. This is simply because the software doesn't recognize it. You will have to disable your antivirus temporarily to install tConfig. Never run any programs you don't trust!


Installing tConfig Edit

  • Download the latest version of tConfig.
  • Run the installer. It will attempt to place the files in your Steam's Terraria folder. If it fails, try placing the installer in your Steam's Terraria folder and running it again.
  • After this, if tConfig crashes, restart your computer and launch again. Unconfirmed: You might also have to close out other programs, notably Skype.

Updating tConfig Edit

Updating tConfig is very straightforward. Assuming you have an existing version installed correctly, you simply need to download the latest version, run the installer again, and it will patch the files it needs to. If everything went smoothly, you should be able to enjoy the latest version!

Uninstalling tConfig Edit

Warning: All your mods are in the same directory as your player and world saves! Be very careful when removing them, or else you may accidentally delete your saves! This is another reason we very strongly recommend backing things up before modding.

In order to perform a clean uninstall of tConfig (To completely remove it from your system), you will need to follow the steps in each category below, to ensure everything is removed.popo

Managing Mods Edit

Installing a Mod Edit

  • Download a Modpack for the mod you wish to use.
  • Place the Modpack in C:\My Documents\My Games\Terraria\ModPacks ( C:\Users\[user name]\Documents\My Games\Terraria\ModPacks in Windows 7)
  • The mod is now installed, but it must be enabled.

Enabling a Mod Edit

  • Launch the game.
  • Go into tConfig Settings from the main menu.
  • To enable the mod,

Deleting a Mod Edit

  • Find the mod in the ModPack folder, located at C:\My Documents\My Games\Terraria\ModPacks
  • Delete the mod. It will no longer show in the options menu.

Note: Please be careful when deleting, as you may be unable to restore a deleted file.

Creating a Mod Edit

  • Please refer to the various tutorials, available from the front page or from this tutorial page.
  • Download the ModPacks Builder here. (used to compile a mod for it to run on Terraria)

Managing a Server Edit

Running a server with tConfig is almost identical to running one in vanilla Terraria. There are two main ways to set it up, and guides for both methods exist elsewhere.



  • A program that spoofs a LAN network connection, which eliminates the need for port-forwarding. However, you will need admin rights to your computer to install this.

Regardless of the method chosen, you would enable your mods in Terraria, and then start the tConfig_Server.exe in the Steam folder. This will allow others to connect using the mods.

Please note: You will need the same versions of Terraria, tConfig, but the server will sync the mods to the client if the client has the same version of tConfig and Terraria.
