Hi tonylfc,
Firefly is the render engine that comes packaged with Poser.
There is plenty of support information that comes with Poser.
I'd be very happy to help you out regarding your render problems but I am a little concerned as to whether you have a legit copy of the program.
If I had just spent $499.00 on a product and it didnt work the way I'd been led to believe I'd contact the makers of the program or read and view the tutorials they offered.
I'm not accusing you of using pirated software but it seems a little odd that you already had poser when I helped you before and now you have a newer version of poser and shelled out $499.00 for the pro version rather than the $129.00 for the basic version yet have no idea how it works.
I'm sorry but if you are using a pirated version I really wont be able to help you.
Maf
