I don't like or use Superfly except to test my freebies because it is way too complicated and way too slow. Over the years, there have been endless threads about how to get something to look right in Superfly. You don't see those about Firefly. There's one thread on the Poser 12 forum right now about how to get skin to look realistic in Superfly. Skin looks fine in Firefly. Criticize me for not wanting to change my work flow, but to me it's about not making my work flow take much longer, such as by having to tweak a bunch of friggin' nodes. When I look at Superfly renders, the only things that look significantly better to me are glass and metal. I don't care about glass or metal.

Now, Poser 12 fixes the speed problem, but it also emphasizes the complexity problem because people are having to waste time because 12 doesn't handle materials the same as 11. Plus, Poser 12 nukes all the Python scripts I use every single day.

I am happy with my results in Firefly. I can quickly test numerous commercial light sets to get just the effect I want. It renders the materials of every product I own. New is not inevitably better.
