Cool of you to notice, 'bear. :) I certaimly would never knock Bryce, but the plant life is one of the major deals about Vue: Vue d'esprit uses these algorithims to "grow" new plant life in accordance with the overall genetic structure of a real plant. The result is that the vegetations are always different, yet conform to pre-defined standards, unlike, say, having a static model which will always be the same. In other words, in Vue the Maple Tree is always a Maple tre, in accordance with the laws that define maple trees, but it wil not be just like the one sitting next to it which you "grew" one minute earlier. :) --Mike
