To install a custom map on a Mordhau server, stop the server, open Mordhau/Saved/Config/LinuxServer/Game.ini in Files, add Mods=<map mod ID> under [/Script/Mordhau.MordhauGameSession] and add the map’s name as a MapRotation= line under [/Script/Mordhau.MordhauGameMode]. Click Save Content and start the server. Custom maps are mod.io mods, so the server downloads them when it starts.

​
Before you start

  • Start the server once, so Game.ini exists.
  • Find the map on mod.io and note two things from its page: the mod ID (a number) and the map name the author gives for the rotation. Map authors list the name to use; it is not always the mod’s title.
  • Make a backup.

Add the map to the rotation

Under [/Script/Mordhau.MordhauGameMode], add a MapRotation= line with the map name from the mod page. The rotation only needs the map name, not a full path:

Save and start

Click Save Content and start the server. The server downloads the map, then plays it when the rotation reaches it.

How to make a custom map the first map

The first map comes from DEFAULT_MAP on Startup, in the format MAPNAME/TYPE_NAME (the default is Grad/FL_Grad). The panel puts /Game/Mordhau/Maps/ in front of it. A custom map needs its full path, which the map author gives. If the author’s path starts with /Game/Mordhau/Maps/, enter the rest of it in DEFAULT_MAP. If it doesn’t, keep the custom map in the rotation, or open a ticket and we help you set it as the first map.

​
How to play only custom maps

With the server stopped, delete the stock MapRotation= lines and keep only your custom map lines. Copy the stock lines somewhere first, or use History in the file editor, if you want them back later.

​
Frequently asked questions

​
Why doesn’t my custom map appear in the rotation?

Check that the Mods= ID is the map’s ID, that the MapRotation= name matches the name on the mod page exactly, and that you restarted the server. The console shows errors if the map can’t load.

​
Can I change to a custom map without restarting?

Yes, with RCON: ChangeLevel <map name> switches the map. See RCON.

​
Do custom maps work with every game mode?

No. Each map is made for certain modes. The mode follows the map name, so use the name the author gives for the mode you want. See game modes.
