Once again I have to thank you folks.

I tried turning off the shadows on the lights, but no luck with the render.

Next, I removed the poly's from the hull that were hidden by the fusion core.  Imported it into Poser, and the weird render stuff was gone from the hull.  Turned shadows back on and things were still good.

I am modeling the Jupiter 2 in Cinema 4D, then exporting to OBJ for import into Poser.  It is taking a bit of getting used to the work flow, but it seems to be working okay.  I can definitely confirm that the landing gear bays are separate meshes from the hull.  When I import into Poser, I am going with the default settings, making sure that "Weld identical vertices" is unchecked so that there is no chance of the individual meshes joining together.

Thanks once again...
