AutoCAD 2013 :: Unable To Render Still Camera View That Shows Lighting And Shadows

I'm creating 3D architectural models; primarily interior views. I use the ANIPATH command quite frequently and I'm good there.

However, I have not been able to render a still camera view that shows the lighting and resultant shadows. Whenever I attempt to render a still from a particular camera; I set it to realistic. It shows the 3D objects with materials; however not the lighting.

I've been using ACAD for about 15 years now, and consider my skill level upper-intermediate.

So far, the only successful still renderings I've been able to do are those directly associated with the typical ortho views: i.e., NE, NW, SE, SW, front, back, etc. But no avail on rendering from the camera point of view.
