Appended layer not rendering any objects I'm something of a noob to blender.  I appended a model of an engine to the 2nd layer of my project, and for some reason, no objects from this model show up when I render.  If I add a cube to the 2nd layer, the cube shows up behind an outline of the engine, but not the engine itself.  The object in layer 1 shows up fine.  For the life of me I cannot find why the objects from this model don't show up.  I have the render visibility turned on for all of them, and I can't find anything else that would change visibility (ie the layer is lit, etc.) 

Can anyone point out to me what I'm missing? Its probably something obvious.  Here is the file: https://www.dropbox.com/s/5q1lnq91oxtpkbg/Blend%20for%20SE.blend?dl=0
Your material is set up for cycles rendering but you have it set to blender render at the top. Then the object in layer 1 is set up for blender internal rendering.
