Remember rexxar's campaign when he transformed into a wyvern in troll islands? First when we arrive in that map, the map is a square, but after we destroy the human battle ships, the map goes rectangle with 1:2 width:height size, with new area discovered. How can we do something like this? I tried to figure out by my own, but failed, please help.
Yeah, blizzard sure use several complicated triggers for their campaign maps. I thought so too, using cam bounds. If we can 'master' this thing we can make a hero to enter the building (with the building map only in the minimap, but without changing the map) or something like that.
