 For example, if we take a humanoid, you do not want to have physical bones for each finger. you can use a single bone for the entire hand instead, or one for the palm, one for the thumb, and a last one for the other four fingers.

 Joints adjustment
 ~~~~~~~~~~~~~~~~~
 
-Once you adjusted the collision shapes your ragdoll is almost ready. You just want to adjust the pin joints to get a better simulation. ``PhysicalBone`` nodes have an unconstrained pin joint assigned to them by default. To change the pin joint, select the ``PhysicalBone`` and change the constraint type in the ``Joint`` section. There, you can change the constraint's orientation and its limits.
