Emission object renders black Inside the barrel of the gun is an object emitting a gradient (purple - teal) light.  You can see the light is being emitted, but the object itself is black.  How do I get the object to render with the material I've applied to it?

Things I've tried:


Clicked on the camera icon right of 'UVMap_final' to activate it as the UV map for rendering.
Disabled auto smooth under Object Data -> UV Maps
Checked to make sure the layer is set to be rendered and isn't masked.
Added a hemi light above the object (although this shouldn't matter, the only object rendering black is one that I have set to emit light).


I feel as though this could have something to do with my node cycle settings (or lack thereof):



Here are close-ups of the object in "Materials" view and also in rendered view so you can see more clearly what I mean when I say the object is black:





Per request below is a screenshot of what the Gun.001 materials node setup looks like:
I found that this problem originated from deleting the extra materials that came with the exported Waveform (.obj) from Photoshop.  I believe this is a unique problem, probably different from the other "help my object(s) render all black" found around here.

To fix this I simply re-imported the original object and left all 5 materials that came with the object.  It's not an ideal solution for me because I would prefer to have one single material applied to all facets/sides of the object rather than have to manipulate and work with 5 separate ones for such a basic shape, however, this works 100% and addresses the source of the problem thus I'd like to close this out.

Example:



If I find further information regarding how to simplify the object's materials into a single mat, I will post that in a new question and link it here.
