I wanted to add some alien plant life to my derelict scene so I tried to make some. Though I have been fighting TreeIt this entire time, crashes, bad exports, etc. For example, sometimes, the geometry comes out broken and breaks lighting, and not sure why. Other times it will export with zero foliage for no reason. Also when you clump leafs, and your scale is too high, they get offsetted and there is no way to offset individual branch clumps that i can find.
The only texture used here is a leaf texture, but it's than turned grayscale and shaded with Terragen. Same for the trunks. Transparency is at 1 for the living leaves, and this is a extreme lighting PT, but they don't seem to have any real noticeable light transmission. I can see Fresnel reflecting the sky, about it. Shadows are very dark even a prong in.
