Another RayShade problem

[Roger H. <rog...@mi...>]

In our interior design program, Microspot Interiors, we set our  
ceilings to back face removed, so that inside the room you can see  
them, but above the room you can see through them into the room. This  
does not seem to work with RayShade. I understand that they must be  
taken into account for reflections, but would it be possible for this  
to be made to work? If so, any pointers on what needs to be changed  
would be useful.

Roger.
