Upload an Existing Terraria World to Your Server

Overview

Fresh Terraria worlds are useful, but eventually another untouched landscape can feel a little too familiar. If you already have a singleplayer world, a downloaded adventure map, or a custom minigame world, you can upload it to your Terraria server and play it with others.

The important parts are simple: find the correct `.wld` file, place it in the server's `saves/Worlds` folder, then set the server's world name to match the file name exactly.

Find Your Terraria World File

On your computer, open the folder where Terraria stores world files. Once there, locate the world you want to use on the server.

Keep this folder open. You will need the world file shortly, and closing the window now only gives you another tiny errand.

Upload the World to the Server

  1. Open your HolyHosting server panel.
  2. Stop the Terraria server before changing files.
  3. Connect to the server using FTP or your panel's file manager.
  4. Open the `saves` folder, then open `Worlds`.
  1. Click Upload in the top-left corner.
  2. Drag and drop the Terraria world files into the upload area.

Wait until every file reaches 100% before leaving the page. An incomplete upload can cause the server to ignore the world or generate a new one instead.

Set the Uploaded World

Return to your server panel and open the world or startup settings.

  1. Find the world name field.
  2. Enter the world name exactly as it appears in the uploaded file.
  3. Do not include the `.wld` extension.
  4. Save the change, then restart the server.

After the restart, the server should load the custom world you uploaded.

Common Problems

The server keeps making a new world. This usually means the file is in the wrong folder, the upload did not finish, or the configured world name does not match the file. Make sure the `.wld` file is directly inside `/saves/Worlds/`, then set the world name without `.wld` at the end.

Players cannot join after the world is changed. Terraria Journey mode can cause this when the world and character types do not match. If your character was created in Journey mode, try joining with a non-Journey character. If the world requires Journey mode, create a Journey character and try again.
