Well guys...first off, thank you for all the advice and information you have provided. Bad news is that it did not work. Alan, I tried the render layers experiment and it failed. The renders still dies out. The info on light linking was useful.

Dann...I forgot about rendering out of Maya with selecting the scene and using render command. I forgot about this since I changed the opening default of all my 3D scenes to DeepExploration. I'll have to give that one a try again.

Good news is that I rendered out just the pipes in sections with primatives as stand ins for my geometry for shadows and it worked. I composited the whole thing in aftereffects. Here is the final image. Suggestions and comments are welcomed. Thank you again. Cheers!
