title: Remove or reduce material bounce
body: <p>I cannot remove the bounce from a stack of multiple objects (using Unity 5.4.0).  Imagine a number of slabs of concrete, 1x1, and height of 0.1.  I'm dropping them flat one on top of the other.  The first two or three act normal, but after 8 or 10 each subsequent slab makes the entire stack bounce and sway as if it were a stack of mattresses.  </p>
  
  <p>Ground uses a mesh collider, and all the other objects are box colliders. All the colliders share the same Physic Material, with Bounciness=0 and Bounce Combine=minimum.  </p>
  
  <p>Project Settings --> Physics: default material is the same as above, Bounce Threshold = 0, and I've even reduced Gravity to -4.0.</p>
  
  <p>The Rigidbody Mass doesn't seem to impact this issue; I've tried everything from 0.1 to 10000.  </p>
  
  <p>I can see some improvement by the changes I've made above, but still, the actual slabs themselves still have this illusive element of bounciness to them.</p>
