Look, can we get over the Python thing already, please? The previous version reached its end of life, they had to move over. Remember PoserPro2014? Same stuff happened when Python versions changed and a bunch of scripts stopped working, and some creators updated and some disappeared and their products bought here in the marketplace became unusable, and absolutely no amount of complaining made it go away. It's the way of life in software development--Python and Poser aren't the only ones. So let's stop the negativity and focus on the original question.

Boni asked a valid question, and it looks like at least from here that Firefly shaders are still vastly preferred based on the sample here. A few of us suggested a survey outside of the forums to reach more users, perhaps via an email blast from Rendo to their subscribed newsletter users: that's a decent sample size. Since this would be for their vendors, it may be a valid option, I don't know, I'm not a vendor, I just have fun making images I'm not making a single cent from.

I think we may need more people chime in here without devolving into Rendo bashing or Superfly bashing, because we have enough of that here already.
