Your initial comparison isn't really valid - the vendor of the Poser product may blithely say the item is easy to use in DS, "simply tweak the materials", but they don't provide a DS native version to double their market any more than the makers of DS products provide a Poser version. The trip from DS to Poser requires DS or the DSON Importer for Poser (and probably Dimension3D's script to browse for a file to load), so it can't be offered as airily, but export and OBJ/use the DSON Importer and tweak the materials would be just as valid as the advice with respect to taking Poser versions to DS. In either case there is a gulf between such quick conversions (which are pretty much limited to Poser 4/ProPack level materials) and a native product for either application that will satisfy store QA.
