Cant say ive ever used the treelab myself. I bought Xfrog for making trees. At $200 for the lite version, its a bargain. Prob is ive not been using it for plants at all, it makes a very nice procedural modeler for abstract models. I will mention that this is the first file to really corrupt for me, other then ones where i messed up and exited while they were still being saved. My concern is that this one im working on is the first in 12 pictures to actually cause real trouble.
