Oh, heavens, I read the "show us your Superfly renders" thread at the official forum, and people spend vast amounts of time fooling with nodes and materials and lighting to get a nice image. When I look at the output, I see no better result except for stuff, like glass and metals, and I'm not interested in rendering glass and metals. I have to use EZ Skin to convert most human figures to even work in Superfly. There's absolutely no reason why Firefly will ever die. It works.
