I use Poser 4 and Bryce 4. The problem still exixts to some degree even when exporting obj. format and smoothing. I am assuming it is due to model quality. Perhaps there is a different smoothing technique that I am not familiar with, which will remedy this. I don't like to add lights that aren't in the reality of the scene. It creates shadows that I might not want in the pic. I think it helps to reduce the shadow intensity in Bryce as most defaults have very heavy shadowing. Still trying for reality in Bryce, Anvilhead.
