How to separate bones from a 3dsMax skeleton?

I am using 3DS Max and I want the bones to allow the deer to fall to pieces; my problem is that the skeleton will force the 3d objects to stick to its bones.

OnCollisionEnter (collider deerBody) {

   //Unparent all objects
   //Skeleton does not interfere or is non present

}

If i can even solve the skeleton solution in 3dsMax and not use code to fix it that would be even better.
