When making cool cinematic shots and whatnot, fog of war is a bummer. It'd be awesome if we could turn it off. As far as I can tell, there isn't a way to do this currently.
Time to make a mod with an invisible unit that gives all radar/sight o3o The band-aid is strong with this one.
Doesn't really help when I'm trying to get footage from an old match, but that would at least be a bandaid.
