Hi Kool Aid,
When I first started using VW Spotlight, I was using it to show room lay out, camera angles, Fire Marshal Drawings, and even 3D models.
All without any lighting!
If your client/producer can visualize well, some times just the wireframe drawings will work. Otherwise just use the ambient light.
It's tricky, but if she is used to working in ACAD, she may see the advantages of the speed and special tools that VW offers.
Good luck & keep the faith!
