Isn't it true: Poser converts 3DS to OBJ for its own use? Taking it in as OBJ gives you control over the mesh without any intrepretation by Poser? It does keep the 3DS texturing, but the nominclature is so strange. For inorganic props, the smoothing function in Poser must be taken into account also. If you can model in OBJ, you probably should, if the prop is intended for Poser.
