Nothing terribly fancy, just looking to see if I could make the explode modifier work with Gen3 tree leaves. This is going to take a lot of tweaking for something nice, but my first pass looks pretty good.
The horizontal motion is purely from the wind field. Vertical motion from a negative Z setting on the particles.
One thing I did hit that puzzles me, is I tried adding some variable force to the wind using an IPO curve. The first attempt, I could see the wind changing with alt-a, but the leaf particles stopped moving. Second attempt, created a new blend from scratch, and the leaves move ok with relation to the variable force wind. Not sure what I did or didnt do properly on the first variable wind test.
