title: Converting coordinates system for FBX model in OpenGL
body: <p>I load FBX models using Autodesk FBX SDK2013.The models get rotated 90 degrees on X-Axis by default.</p>
  
  <p>The SDK supplies this method :</p>
  
  <pre><code>FbxAxisSystem::OpenGL.ConvertScene(scene);
  </code></pre>
  
  <p>to perform axis conversion.But it doesn't work.Calling it changes nothing.Moreover,it seems that the FBX exporter uses OpenGL right hand sytem by default,at least that is what it says on import:</p>
  
  <pre><code>     FbxAxisSystem fbxAxis = scene-&gt;GetGlobalSettings().GetAxisSystem();
  
              if (fbxAxis != FbxAxisSystem::OpenGL)
              {
                        //....
              }
  </code></pre>
  
  <p>returns false.
  So I don't understand;if it is OpenGL (right handed system,why the models have Z axis as up?
  Is it the SDK bug?</p>
