Yeah Hawk I totally agree, a nice Vol. texture would work very well, ALSO..another good way to trick the volumetric world is to use the RGB perspective in conjunction with the haze and fog, not only in colors but in base height etc, also adjust your sun's position and color to work with those. that's all with Bryce 4 and the Skylab if you have that version:-0

Do atleast one thing a day that scares the hell outta ya!!
