How to add mods to your Terraria tModLoader server

  1. Stop the server and install tModLoader from the Mod Manager button in the game panel.
  2. Go to the File Manager button and upload your mods inside the folder \tmodloader\ModLoader\Mods\.
  3. Go to the Configuration Files button and enable the mods inside the enabled.json file.
  4. Start the server.

Enable your mods in enabled.json

When enabling the mods inside the enabled.json file, you need to list each mod per line with the correct mod name (case sensitive). Don't add a comma to the last line, like the example below.

[
    "CalamityMod",
    "WonderInventory"
]

Here CalamityMod (the Calamity Mod) and WonderInventory are examples: use the exact internal names of the mods you uploaded.

tModLoader mod questions

How do I add mods to tModLoader on my Terraria server?

Stop the server, install tModLoader from the Mod Manager, upload the mods to \tmodloader\ModLoader\Mods\ with the File Manager, list each mod by its case-sensitive name in enabled.json under Configuration Files, then start the server.

Why won't my tModLoader server load my mods?

Check enabled.json: each mod needs its correct, case-sensitive name on its own line, in quotes, and the last line must not end with a comma. Also check the mod files are inside \tmodloader\ModLoader\Mods\.

How do I add the Calamity Mod to my server?

Upload the Calamity Mod file to \tmodloader\ModLoader\Mods\ and add "CalamityMod" to enabled.json, as in the example above, then start the server.
