How to Add Steam Workshop Mods to Your Space Engineers Server

Updated 10 June 2026 · By Host Havoc Technical Support Team

Steam Workshop mods can be added to your Space Engineers server directly from the game control panel using the built-in Workshop Mod Browser.

Before adding mods, also make sure the World Name in SpaceEngineers-Dedicated.cfg matches the active save. A mismatch will prevent mods from loading. See Fix Mods Not Loading if you run into issues after installation.

Before you start: A world must be generated on the server before you can install mods. Mods are tied directly to saves.

Steps

  1. Log in to the Game Control Panel and navigate to your Space Engineers server.
  2. Click the Steam Workshop icon.
  3. Find the mod or mods you want to install and click Install next to each one.

  4. Restart your server.

Once the server restarts, the mods will be active. You can monitor the download progress in the Web Console while the server is starting.

Tip: If mods are not loading after installation, open LastSession.sbl in Configuration Files and verify that the path matches the World Name set in SpaceEngineers-Dedicated.cfg. Then click Steam Workshop (Installed) and select Reinstall All.
