[Radiance-general] Modelling of a lightshelf

[Lars O. Grobe]

Hi Virginie,

for the reflector to be considered properly with direct sun exposure, 
you need to model its surface using the mirror modifier.

I gave an example (as I was not sure about the way how I derived the 
values from a metal surface) earlier this month. Subject was "virtual 
light sources with mirror & diffuse component", date 2.8.2012.

Cheers, Lars.
