Rendering Issue - Tracked Video & 3D Object Composite When I render the scene, only the tracked video appears; the 3D objects do not render. However, the objects appear if I set my active view to rendered (Shift-Z). "Restrict Rendering" is inactive. 

After rendering, this message appears: 


  No Layers in Render Result
Might be an obvious one, but check your render layer setup and which layers your objects are on... 


Also check your compositing node setup after rendering an image. I've had problems in the past when I accidentally moved objects to layers that were selected as a mask layer or Excluded layer.
