Hi Obi van, Solid Growth is E-on's invention for creating trees and it only exists in Vue--no 3rd party plugins. Try this. Grow a tree of some sort and in the "summary of materials" window, load a solid color in place of the leaves. Then grow a few more of the trees and do the same thing and see what you now have after rendering. The appearance of the tree leaves is actually based entirely on the transmaps and materials/butmaps, and is not a polygon mesh at all. Hopw do they do it? I don't know, and that's a carefully guarded secret they have. But, by altering the existing materials, you can come up with lots of your own new plants. Experiment!
