If you want to have admin rights on your V Rising server, it's super easy!
Before any manipulation, go to the manager of your server, and stop it.
Once the server is stopped via your manager, simply go to the Configuration tab, you have the adminlist.txt file, it is in this file that you will be able to enter your steam ID.
Where can I find my Steam ID? Generally, you just have to go to your steam profile, and a URL is displayed, it looks like this: https://steamcommunity.com/profiles/monSteamID
You will find a series of numbers at the end of this URL, that's what you need to retrieve and copy paste into the configuration file named adminlist.txt.
If you have a custom steam ID, you can use this site to find it https://steamid.io/ , it is the Steam ID64 that should be copied.
If you want to have several admins, the manipulation remains the same, however you must enter one steam ID per line, without any additional characters.
Like this:
And don't forget to save!
And now you can restart your server once the changes have been entered and saved.
Now, you have to display your ingame admin console, it is not activated by default.
Once the game is launched, go to the options, general, and you have to check the activated console box.
Once done, you can connect to your server and click on `(ALT GR + 7 on French keyboard) to open the console and enter adminauth. You are now admin of your server and you can use the commands you want via this console.
You can find the list of admin commands on the game wiki:
