Hi guys,
Hope this is the right place to post for my question.
I’ve created a tree mesh with various single polys for the leaves. Question is how to i get that nice effect of the leaves blowing in the wind? Is this done via script on each individual poly or is there a simply way in Unity? Or am i making this way more complicated than what it needs to be? 
Hi,
Could use shaders for that, look for waving grass shaders in the forums,
and/or download the builtin terrain grass/leaves shader sources for examples:

If you want your trees to use the windzones, then you will probably want to emulate what the trees from the tree creator do.
The shaders they use give them that effect.
You can use those shaders on your trees. Apparently they get their values based on the alpha channel of the vertex colour? So, you paint on the alpha channel and depending on how white it is on any particular vertex, that is how animated it will be… or something. I don’t even know what that means, but I read up on it once.
