Blender 2.77a to unity 5

Hello Community
I want to import my mesh from blender 3d to unity but the problem is that the physics (is active , is passive) thing under physics in blender is working but in unity it is not working ,

Also it is not collider even after generating colliders (my mesh is little bit complicated to create custom unity colliders)

If I use rigid body with colliders then it shows error about non kinematic with non convex collider … something like that

If I make it convex then it shows that mesh have to less then 256 vertices error

If I animate physics with collider then it doesn’t collider .

I tried exported with .blend, .obj, .fbx but nothing works .
