I see problems with reversed faces in your model but as far as the displaced panels, I think that’s a question for the Indigo Renderer folks. I get this in a quick render with Kerkythea. I didn’t bother to set the materials up because that part is unimportant for the question at hand.
Here’s an animation to show what @DaveR mentioned about reversed faces. To generate this, I set the back face color to a neon green and set the rendering style to monochrome. There is also an issue with two faces at the same location causing z-fighting that I wave the cursor over near the end.
