title: Qt3D - Import gltf and play animation
body: <p>I'm currently struggling to play the animation of a gltf-file with Qt3D/QML.</p>
  <p>Model I want to use:</p>

  <p>Code I have so far:</p>
  <pre><code> Entity {
      id: root
  
      Transform {
          id: planeTransform
          scale: 0.1
      }
      components: [
          planeClip,
          planeTransform,
          planeScene
      ]
  
      SceneLoader{
          id:planeScene
          source: &quot;qrc:/Modells/3DModelle/plane/scene.gltf&quot;
      }
  
      AnimationClipLoader{
          id: planeClipLoader
          source: &quot;qrc:/Modells/3DModelle/plane/scene.gltf&quot;
      }
      ClipAnimator{
          id: planeClip
          clip: planeClipLoader
          channelMapper: ChannelMapper {
              mappings: [  ] // Dont know where to get this
          }
  
          loops: Animation.Infinite
          running: true
      }
  
  }
  </code></pre>
  <p>I use the SceneLoader to check if the gltf can be even loaded (it works, I can see the plane).
  But I'm struggling to start the animation because I don't know where I get the ChannelMapper from.</p>
  <p>When I open the file with 3DViewer on Windows, it plays the Animation correctly, so I suppose it should work without much insider knowledge of the file itself.</p>
  <p>Anyone here familiar with playing gltf animations?</p>
  <p>Thanks for the help!</p>
