Are you using hard/soft edges in wings?  It is actually recommended practice when modeling to bevel hard edges >>very<< slightly as a final step, and Poser does much better with meshes made this way.  The most important thing is to look at the object's crease angle in its properties.  Set it to whatever value looks good for each object.  If your object (e.g. a house) had 90 degree edges before beveling, the beveled edges will be 45 degrees.  You'd want the crease angle to be less than that to keep those edges looking sharp in Poser.  I recommend lowering the setting until you see something creased you think should be smooth, then raising it enough to smooth that area.  

This room and its props were modeled in Wings, and if you look closely you can see how the beveled edges much improve the look of the props.
