Hey hey I found an app that is quite interesting for generating low poly count plants- that look really good actually..... its called Plant studio

you can export the files as lwo which is really cool
there are also video tutorials available to teach you how to use it- just google it and you will find them
I rememeber there was a thread a while back where we had 2 other plant generators- I couldnt find it tho, but it would be cool if we could put this thread with those if anyone remembers where that was
