"..why didn't I see this before? Sigh... Just bought the new Vray, which is giving me endless trouble. Because I can t(yet?) render with that, I downloaded the iRender demo. It's excellent! Beautiful results, absolutely on a par with Vray; far more intuitive interface; and some nice environment options too. It renders a big model that makes Vray crash without a glitch, and pretty fast at that. So much for impulse buying. I'm seriously considering getting this anyway."
