How to upload a custom world to your Terraria server (Vanilla)
Step 1
Stop the server and find the custom world file on your PC. The file name should have the .wld extension. For example: My_World.wld
The worlds in Terraria are saved in the folder Documents > My Games > Terraria > Worlds on your PC.
Step 2
Now go to the File Manager in the game panel and upload the .wld file inside the folder: saves > Worlds of your server.
Step 3
From the Startup tab of the game panel, under "World Name", you need to specify the name of the world you uploaded so that when starting the server, it loads your custom world. Make sure that the world name matches exactly with the name of the file you uploaded, without the .wld extension.
Step 4
✅ That's it! You can now start and join the server with the custom world. If you have any problem, contact us by Discord (opens in a new tab) so we can help you.
