AbsoRayne 0 Posted June 12, 2009 I have a map in the making, and one of the key problems as I watch AI's battle it out in Skirmish, is that any air used in the map flies over the Mountains, and basically wrecks a base without thinking. I tried to use the brush setting for Impassable to Air, and its grayed out, and I cant seem to figure out how to change that. Can anyone give me a hand here? Share this post Link to post
