title: Rigged mesh doesn't animate (despite the bones moving)
body: <p>I have a model with a skeleton, all set up.</p>
  
  <p>I've added the animations and Animation Helper to see the model move.
  The result is odd - the bones are moving (according to animation helper rendering), but the actual model itself does not.</p>
  
  <p>It's better explained with an gif:</p>
  
  <p><img src="https://i.stack.imgur.com/BHaS3.gif" alt="problem"></p>
  
  <p>Animation is attached to the mesh using:</p>
  
  <p>animation = new THREE.Animation( mesh, geometry.animation );</p>
  
  <p>Any suggestions on what might be wrong?</p>
