There are a LOT of things SuperFly does natively that FireFly needs to be told to do. AO is one of those things. Any of the "Raytraced" add-ons for FireFly and not needed for SuperFly. Reflections for example are just always present in SF. For the most part SF will just ignore those nodes. Node connections that won't work for SuperFly are represented by a dotted line in the material room.
