I had to model it so it could fit in the 2d drawing, but I didn't want any light coming from the slice, so I modeled an extra space on the other side to which I added a white material with almost 0 opacity (if I went down to 0 octane started to stall on me). Since the sun doesn't go thru opacity maps it worked well blocking the sun meanwhile it didn't obstruct the view.
Here is the result plus the wip of the setup.
Since we liked we added an extra camera for that interior shot.
We hope you liked. (And we hope he gets his degree, too

Cheers
