I was just speaking as a casual Poser hobbyist.  That's the only render engine I deal with ;)  It does make me smile though when I see the long threads that can get so hyper critical of people's meshes, and then I look at items with mesh that just looks awful . . . but . . . renders just fine.  At that point some of the purist stuff just starts to sound like idiosyncracy.  To me if it renders well then the mesh is good.  I don't care if it has a lot of tri's, or long polys, or whatever.
