the dustcloud is one of those elongaged sphere thingys and I applied a cloud as the texture, then went into materials and adjusted the colors...duplicated a couple times moved the duplicates around and there you have dust clouds... The highlights are not so hard to add, basically I did a texture that was a bit multicolored to start with, then adjusted the lights in Bryce also. You have to diddle with it a bit but with a little practice it comes out alright... just try and if you don't like it undo...if it looks ok, then save....try some other stuff. that is the neat thing about using digital materials, there is no mess, no redo'ing everything if it goofs up....(only have to look out for system death...!...but if you save often then go back and dump the images you don't need...also you can go different ways with the same picture.
