OverrideDropshipMapImage
Tracking Issue: #1524
An image of the objective parcel is fetched for the dropship briefing screen, while players are waiting for the mission to load.
This hook runs in XComPlayerController::UpdateUIBriefingScreen, which uses SelectMapImage in XComMapManager to fetch a map image path for the briefing screen.
This hook runs after the image is picked, and if OverrideMapImagePath was modified to not be an empty string, it will be used as the map imagepath instead.
Parameters
OverrideMapImagePath: An empty string used to override the map imageObjectiveMapName: String which was used as a parameter forSelectMapImageChosenMapImagePath: String which was the result of the function call toSelectMapImage
You can use 'MAPS.SelectMapImage("MyMapName", "OptionalBiome") to find an existing image definition or arbitrarily assign any string to OverrideMapImagePath
