I'd have to agree that Vue does nice skies and pretty good volumetrics, but, Bryce seems to be alot easier to use and achieve fairly quick results. I have Vue 4, and every now and then am tempted to give it a chance, but, I'm just to damn faithful to Bryce. Let's just hope that DAZ listens to all the faithful and makes Bryce better than Vue, World Builder and Terragen combined, and keep it affordable so that people of all skills can pick it up.
