To activate the whitelist you need the group ID. To do this, you need to follow these steps:
- Create a group on Steam and invite your friends.
- Log in to Steam via the browser (at store.steampowered.com)
- Go to the group you just created
- Now you have a URL that looks like this: https://steamcommunity.com/groups/nameofgroup
/memberslistxml/?xml=1after the URL and press
- In the second line you will find your group ID under the line
- This is your group ID
- Go to the directory of Space Engineers and open the file
SpaceEngineers-Dedicated.cfgand scroll down to the very bottom
- Add the line
<GroupID>0</GroupID>and replace the
0with your group ID
- Save the file and restart your server
All members you want to whitelist must be in the group. Once the whitelist is activated, only members who are in the group and therefore on the whitelist can join the server.
