The problem arises with the use of the PoserSurface node for Superfly rendering.  Try connecting the PhysicalSurface node to BB's shader array and you will get a different render result.  My suspicions center around the usage of the Translucent feature in the original setup but I can only verify that by meticulously pulling every connector apart and replacing every node with Superfly-specific nodes.  In all reality, if you are serious about embracing Superfly-rendering as your primary workflow, I suggest making a clean break from the PoserSurface node as your root base.
