I could believe that you didn't get much if you used the volumetric world with quality set over to the high side. The image looks like it would have been awesome, if you ever have the patience tolet it run. You mighht try checking the quality setting on volumetric worlds, try running it with something less than 50. You might lose some of those rays that your fist image only hints at. Ya gotta love what Bryce can do. Someday the hardware will catch up with it and we'll be able to use some of these jewels.
