[3dsMax 2011] Skinned Mesh with bones missplaceds

Hi there,

I've trying to export from 3dsmax a skinned mesh character wich all the bones would be controlled by Script.

but when I import, all the bones come missplaceds and with a wrong pivot point. (yet all hierarchy is ok).

Does anybody here can tell me how to succeful export from 3dsmax to unity3D and keep the bones working?

Thanks!
