Looks good. There's still some tweaking to be done. Sorry I haven't responded in the thread, some RL issues I have to deal with... all my modelling work/aid/requests are sort of put on hold for me. But this looks good sofar...
I agree with the critisism though. Leaves turn around the Z axis as well. There's still a millisecond where these leaves JET upwards from the ground back to the sky, which should be removed. I like the different stand anims, but some leaves should rotate more.
All in all, it looks very good sofar, but just not really natural yet. With a bit more tweaking, this thing would be perfect.
I have found something that may help us. Look in War3.mpq with the War3Viewer for three "sharedmodel" named 'feather1', 'feather2', and 'feather3'. These should give you something to work with by getting the leaves to turn the natural way.
