You can't. The only solution I can think of is to collide with an invisible B3D proxy or similar. You may have problems syncing up animations tho.
Wait a minute.. you can't collide with the animated b3d mesh anyway. What exactly are you trying to do? You would have to collide with animated bounding boxes/spheres.
