Anton - are you aware that (according to the information in Tirjasdyn's linked FAQ) if the shading rate setting (which every Poser actor has in it's parameters window) is higher than whatever minimum that you might have set in Firefly, then it will override your Firefly setting? Firefly will use the highest of the two values.
