Dianethe particle effect is a special fx prop by aksiel I dl'd from the Props Guild. The lights I made in Poser using various transparency/reflection/ambient light combos with a lens flare applied in Photoshop later. I find that's a neat trick for making lights "glow". Poser can't do that. The atmosphere is a green marble texuture applied to the ground and a HUGE single-sided square in the background. Tried the Bryce demo I got at Seybold yesterday. So cool! I can't wait until the real thing arrives!
