Smoothing doesn't smooth the mesh, it smooths the normals which is just a render trick! Edges and shadows are based on the mesh and will always show up as faceted. The only solution for edge faceting (roughness) is a higher density mesh, which Bryce can't do. Repeatedly clicking smooth will produce the same normals every time. Setting it to 90 is good for "poser" like objects but for stuff that has sharp edges it needs to be set to something less then 45deg cause there isn't a good normals solution for these and they end up lookong really odd. .OBJ/.3DS usually have smoothing data included but not always (like exports from ZBrush).
