The importation and exportation to 3D Max and Lightwave were superficial features added to ProPack, not main features, since Poser already imported and exported to those programs to begin with. The reason they're not in Poser 5 should be rather obvious by now. Poser 5 is the superior program in the Poser world, hence the reason it is Poser 5. ProPack is the "expansion pack" of the Poser 4 series. Poser 3 is before Poser 4 and after Poser 1 and 2.
