Poser 5, still has Poser 4's renderer. You can use that until you get familiar with firefly. I would recommend installing P5 on a newer machine. I first installed P5 on a 500MHz Athlon machine running Win98. It ran okay but was very slow. Upgraded to a 2.8gig, Win XP machine with a gig of RAM and it runs like a racehorse. With latest updates, it is very reliable for me.
