Quote - Native and Transposer.  The only difference between them is that Transposer supports dynamic hair and cloth while the native import does not.

No, the difference is that native import tries - like DAZ Studio - to import all kind of Poser content natively into Carrara, that means it creates bones for figures and you can pose the imported figure afterwards. But it's much bader at that than DAZ Studio at the moment. Transposer needs Poser because it passes Scene files (and it can't import anything else) "through Poser" and only gets a solid mesh for each figure by that process. So you cannot pose the result, cannot apply (MAT) poses in Carrara afterwards as you can with native. But Transposer will import dynamic hair and clothing correctly and of course also magnets (as it imports the deformed mesh) - native import can't do that.
