You know, I've seen some really interesting challenges and thought to myself "hey, that might be fun to try" and then I get to the "and must be rendered in Bryce" and out the window it goes. Guys, could you all try to keep in mind that not all of us have Bryce? I have NEVER had a copy of Bryce. Now, for those challenges where a specific preset or material or bryce object is involved, I can understand why bryce would be required. But for those where the challenge is one of lighting, mood, theme, etc, why not just let the participants use whichever renderer they prefer? Kate (who doesn't participate in these challenges cuz almost all of 'em say "and render in Bryce")
