custom tree from 3ds max doesn't bending

Hello kind people!
Sao I created tree (norway spruce), expoted to *.fbx format, put material → soft occlusion leaves and soft occlusion bark, added capsule collider, mede a prefab, plased trees using terrain tool, added wind zone (directional) and nothing moves!!!
is it a bug?
or did i modeled something wrong?
is it possible to add custom tree into tree creator inside unity?
if possible then how?
am i need to paint vertex colours for tree bending?

I’m using unity 4.1.5

P.S.
advanced terrain shader dont work with custom trees otside tree creator…

For externally modeled items. you probably need to animate in max then script it to activate with code
