The best way to transfer between Carrara and poser is to export from carrara as an obj using the poser defualt selection and ensuring that the proceedural materials are select to export as images no less than 512x512. Once exported it can then be imported into poser and then rigged up (and that is where my brain drys out LOL).

BTW - noviski.. I would only suggest the best.. and you're the one for this kind of work.
