title: How can get all Key Frames(Key Ticks) in 3DS Max using its SDK
body: <p>Right now I can get all Key Frames(Key Ticks) out of My skinned Model using 3DS API, if my model has a 
  Transform Controller and at the same time this transform controller has Translation Controller and Rotation Controller
  using:
    Control* pos_max_controller = current_igame_node->GetMaxNode()->GetTMController()->GetPositionController();
    Control* rot_max_controller = current_igame_node->GetMaxNode()->GetTMController()->GetRotationController();</p>
  
  <p>But I found, a skinned model can also have other kinds of transformation controllers underneath that Transform Controller(maybe Some Spline Controller).</p>
  
  <p>But in this case, I just can get that translation controller( even if it is not lying underneath TM Controller). 
  And that rot_max_controller in this case is always 0.</p>
  
  <p>How can I handle any kinds of Transform Controller with any kinds of kid controllers using the 3DS Max API?</p>
  
  <p>Thank you very much</p>
