One of the posts above stated they do not use the Firefly renderer.... doesn't that then exclude many of the new features, such as the strand hair ???? So why even bother to run it at all....everything takes so much longer to do in P5..I think I would just uninstall it and go back to P4.

Humankind has not woven the web of life. We are but one thread within it.
