How To Create A Valheim Custom World

Creating a custom world in Valheim lets you tailor the Viking experience to your liking—perfect for solo adventurers or friends seeking a unique map layout. Whether you want easy access to bosses or a scenic base location, Valheim’s world generation options give you control over the terrain and biome distribution.


In this guide, we'll cover how to create a Valheim custom world so that you can use the desired world seed on your Valheim dedicated server. You can choose from a lot of unique Valheim seeds, such as ones with a small starting island that transitions into a large Plains biome, which is ideal for advanced players. This can give a better experience in playing on your Valheim server, and have much more fun.


Note: This requires you to have the PC version of Valheim, which will allow you to copy the world from your local installation to the server.


Note: You will also need to disable cloud saves to retrieve both .db & .fwl files.


Step 1: Disable Cloud Saves


  • Open Steam


  • Navigate to Valheim


  • Right-click and click Properties


  • In the general tab, disable Steam Cloud

  1. On your keyboard, use Windows + R, and head over to C:\Users\pc\AppData\LocalLow\IronGate\Valheim\worlds_local


  1. You'll be using both the .db & .fwl files of your world you just created

  1. Open your Apollo panel


  1. Head over to the Files Manager
