All the circled nodes below are problem spots.

Reflection_Color and Reflection_Value connectors are typically reserved for metallic surfaces and are common in Firefly, but do not render well in Superfly.  The Sphere Map node is a reflection cheat in earlier versions of Poser, it is unnecessary and needs to be removed.  

Reflection_Lite_Multi check box should be unchecked.  Failure to uncheck it is a very common mistake made by many content creators.  This is also associated with very reflective metallic surfaces.  

I notice that the Image map is connected to both the Diffuse_Value and a Blender Node associated with the Bump Channel.  As a rule, maps connected to Specular, Bump, Displacement, and Transparency connectors should be set to a Gamma value of 1.  In this case, if the Image map has a default Gamma value of 2.2 (Render Setting), you will get bizarre results in those mentioned channels.  It is best to connect that map through a Gamma node set to a value of 1.
