title: Collada to SceneKit to iOS
body: <p>I have a collada file, it contains a cube, from this I export the data to a file (just raw bytes), and I import the bytes into iOS.  All good, I examined the data and all looks the same for vertices on iOS and osx.  </p>
  
  <p>However when I examine the Collada file, the normals are very different from what SceneKit has</p>
  
  <p>In SceneKit the normals are either 0, -1 or 1.  In the Collada file I have -2.831...,-1.31..., etc.</p>
  
  <p>Any insight appreciated,</p>
  
  <p>Thanks</p>
