title: Export DAE animation from 3ds max to Xcode with correct bounding box
body: <p>I'm trying to convert some fbx animation to DAE file in 3ds max, and then use it in Xcode with SceneKit. It almost works, but there is a problem when I'm trying to get bounding box of this node in SceneKit. Bounding box seems to be much larger than node itself. It also shows when I try to add Physics body in Xcode. Probably I need to do something in 3ds before exporting, but I don't know what. Does anyone know how to prepare such animation, so that bounding box will be responding to node size?</p>
  
  <p>Code for loading model is very simple: </p>
  
  <pre><code>let scene = SCNScene(named: "(model.name).dae")!; 
  object.model3D = scene.rootNode.childNode(withName: "MDL_Obj", recursively: false)! 
  </code></pre>
  
  <p>I think that bounding box itself is correct, but this animation is transformed, scaled or something (I'm not an expert in 3d). Bounding box is 90x131x22 - same as physics body in Xcode scene editor, and the person in animation itself is more than 2x smaller. </p>
  
  <p>Here is this animation, maybe someone can help. </p>
