Lets say your playing on the bedroom map, and you build something on the roof. You then decide to buil something WAY out in the grass, so far that if you look back at the bedroom, you notice that it is starting to become white (which means it is being effected by the fog). but at the same time you are looking back you notice that whatever you just built on the roof is not turning white at all (so it is not being effected by fog).
clear as mud?
