How to add Mod.io mods to your Space Engineers server

Before Mod.io mods can work properly, crossplay must be enabled.

Step 1: Please stop your server.
Step 2: Click the “File Manager” icon and navigate to your save’s Sandbox_config.sbc, and Edit it.
Step 3: In a new browser tab, visit the Mod.io website and locate the Resource ID for the mods you would like to add.
Step 4: Copy the Resource ID. For example, the ID would be 451208.
Step 5: Return to the browser tab with your Sandbox_config.sbc file and locate the <Mods /> section.
Step 6: Update the <Mods /> section so it looks like the example below, adjusting the details to match the mod or mods you want to add:

<Mods>
  <ModItem FriendlyName="Assault Weapons Pack">
    <Name>451208.sbm</Name>
    <PublishedFileId>451208</PublishedFileId>
    <PublishedServiceName>mod.io</PublishedServiceName>
  </ModItem>
</Mods>

If you are adding multiple mods, you can include them like this:

<Mods>
  <ModItem FriendlyName="Assault Weapons Pack">
    <Name>451208.sbm</Name>
    <PublishedFileId>451208</PublishedFileId>
    <PublishedServiceName>mod.io</PublishedServiceName>
  </ModItem>
  <ModItem FriendlyName="Astion Miner for Space Engineers">
    <Name>1813919.sbm</Name>
    <PublishedFileId>1813919</PublishedFileId>
    <PublishedServiceName>mod.io</PublishedServiceName>
  </ModItem>
</Mods>

Step 7: After adding all desired mods, click “Save & Exit”.
Step 8: Start your server so the mods can begin downloading.

You can keep track of the startup progress by opening the Web Console while the server is running.

Please note that some mods may require a new save to be created in order to be installed or uninstalled successfully.
