There are several forum threads dealing with optimizing material shaders for Superfly rendering.  Although some of the older content with simplified node arrangements might render well in Superfly, there are significant changes that need to be made to truly create physically based rendering (PBR).  In essence, you get rid of all the hacks that were invented in earlier versions of Poser and render images with realistic responses to its 3D environment.  There are some tutorials available, but I would need to do a deep dive to find some good ones.  If you proceed as far as using Cycles in Poser, then there are many Blender YouTube tutorials available that can give you an introduction.
