Properly set up lighting scenarios for options

Hi alll,

I am working on a project where the ceiling can be changed from flat to coffered and I’m not sure the best way to build the lighting on this.

My current setup is to have all the walls and floors on the persistent, a sublevel called Coffered and a sublevel called flat. I have been playing with some of these being lighting scenarios but I am not getting the results I need, ie. shadows being cast from coffered onto flat.
The experience opens up with coffered ceilings and with the press of a button it will toggle the flat scenario.

Whats the best way to do this?
