I do realise that mate, but what i am trying to say instead of saying [mission file] & [addon file] is to combine them as [mission file[addon file]], so that the addon is downloadable with the mp mission, otherwise no-one would be arsed the download an addon separately just to play the mp mission.
The long winded question i am trying to ask is... Is there a way to tell the game engine to reference config files from a different directory, other than the mod directory?
