Can I create an isolated Fog of War on a map instead of having the entire layer under fog? Let's say I have a cabin where they bad guys are holed up. The group has the place surrounded and know they've got to go in. So, the outside is all clear, but it's the building that is fogged only.
Would I have to build big swaths to cover the outside and just turn them off? It would be nice to have the ability to put just isolated fog patches and not have the entire layer fogged.
