Icarus ServerSettings.ini Explained: Every Server Setting

Icarus dedicated server settings live in Icarus/Saved/Config/WindowsServer/ServerSettings.ini, under the section [/Script/Icarus.DedicatedServerSettings]. The file holds the join password, admin password, lobby rules, start-up prospect and idle timers. Icarus does not create it on the first start, so create it in Files, edit it with the server stopped and restart. The server name is set on Startup, not here.

How to create or edit ServerSettings.ini

Stop the server

Open your server in the Game Panel and click Stop.

Open the folder

Click Files and open Icarus > Saved > Config > WindowsServer. After the first start it holds only GameUserSettings.ini.

Create or open the file

If ServerSettings.ini is there, click it. If not, click New file, paste the template below, click Create File, enter ServerSettings.ini as the File Name and click Create File.

Save and start

Click Save Content after any change, then Start.

The full ServerSettings.ini template

This is RocketWerkz’s official template with all defaults:

[/Script/Icarus.DedicatedServerSettings]
SessionName=
JoinPassword=
MaxPlayers=
AdminPassword=
ShutdownIfNotJoinedFor=300.000000
ShutdownIfEmptyFor=300.000000
AllowNonAdminsToLaunchProspects=True
AllowNonAdminsToDeleteProspects=False
LoadProspect=
CreateProspect=
ResumeProspect=True
LastProspectName=

What each Icarus server setting does

Key	Default	What it does
`SessionName`	empty	Does nothing on current versions. Set the name with Server Name on Startup.
`JoinPassword`	empty	Password players need to join. Empty means no password. See set a password.
`MaxPlayers`	empty	Players allowed at once. Leave it as it is: your player slots come from your plan, and you can open a ticket for more.
`AdminPassword`	empty	Password for `/AdminLogin`. If empty, anyone who uses `/AdminLogin` gets admin rights, so always set it. See become admin.
`ShutdownIfNotJoinedFor`	`300.000000`	Seconds the server waits for a first player after loading a prospect, paused. Then it returns to the lobby. Below 0 waits forever, 0 returns at once.
`ShutdownIfEmptyFor`	`300.000000`	Seconds the server waits after the last player leaves, paused, before it returns to the lobby. Below 0 waits forever, 0 returns at once.
`AllowNonAdminsToLaunchProspects`	`True`	`True`: anyone in the lobby can create or load a prospect. `False`: admin login needed.
`AllowNonAdminsToDeleteProspects`	`False`	`True`: anyone in the lobby can delete prospects. `False`: admin login needed.
`LoadProspect`	empty	Save name of a prospect to load at start-up, from `Icarus/Saved/PlayerData/DedicatedServer/Prospects/`.
`CreateProspect`	empty	Creates a new prospect at start-up: `<type> <difficulty 1-4> <hardcore true/false> <save name>`. See prospect settings.
`ResumeProspect`	`True`	Resumes the prospect in `LastProspectName` at start-up. See resume prospects.
`LastProspectName`	empty	The last prospect the server ran. The server fills it in.

Good settings for a private server with friends

JoinPassword=wolfpack2026
AdminPassword=Str0ng-Admin-Pass
ShutdownIfNotJoinedFor=-1
ShutdownIfEmptyFor=-1
AllowNonAdminsToLaunchProspects=False
ResumeProspect=True

With -1 the prospect stays loaded when nobody is online, so players join straight into the world instead of the lobby.

Frequently asked questions

Where is ServerSettings.ini on an Icarus server?

In Icarus/Saved/Config/WindowsServer/. If it isn’t there, create it. Icarus does not make it on the first start.

Is there a difficulty setting in ServerSettings.ini?

No. Difficulty belongs to each prospect and is chosen when it is created. See difficulty and hardcore.

Why are my changes not working?

The server reads the file when it starts. Stop the server, check the file name, folder and the section line at the top, click Save Content and start it again.

What is GameUserSettings.ini for?

It is an engine settings file the server creates itself. Icarus server settings don’t go there.
