To add these kind of markers:
- In the World Editor, and through the Resource Browser area, go to ArmaReforger > Prefabs > ScenarioFramework > Components;
- Drag and drop somewhere on the map an Area.et;
- Drag and drop a Layer.et into the Area created in the Hierarchy tree;
- Now, for each faction marker you want to create, do it:
- Drag and drop a SlotMarker.et into the Layer recently created and listed in the Hierarchy tree;
- Click over that SlotMarker created, go to its properties, and click on SCR_ScenarioFrameworkSlotMarker;
- Through the Map Marker area, give the marker a name, and select its icon, and color.
P.S: for some reason, the “Faction Key” field shouldn’t be used, otherwise the marker won’t be shown for any player, even the configured faction.
