Thanks! right. The manual does cover that, although it confused the heck out me when I first started. My question is, can it be converted into a bryce material - like the ones alread in there. In those materials, you can change one or all of the colors in the texture editor as well as adding effects like distance fuziness, make it a volume material etc. If so, what needs to be done? The manual is very technical on this whole area, and a little bit beyond me. Thanks again Aharon
