[Radiance-general] reflector size

[shailan zareiy]

Dear Christopher and Greg
The problem i told is that ,for example a light shelf with width of 0.2m
increases the illumination of the zone more than a shelf with the width of
0.5 or more. but it seems that it is solved when i increase the resolution
,with increasing ad and as.thank you for your help.
i have another question that is how can i make a diffuse reflection from a
mirror material as a secondary light source
Thanks
Shailan
