If you use any 3rd party Pythons, you may want to wait. None of those work as the language has been updated to version 3. Some are working on updating a few essential scripts. Also be aware most previous Superfly mats released for purchase look like crap in new Superfly as Cycles nodes have also been changed.

If you are brand new at Poser or only use Firefly and never used 3rd party scripts, go ahead.
