I am running a daylighting analysis on radiance by exporting it out of Ecotect. I get drastice difference in DF levels with and without camera view. for eg. with camera I am getting 2.02% and w/o camera am getting0.96%. Could some one explain why this is occuring?

Thanks,

I am running radiance( for DF factor and Illuminance (Lux) on a building:
its a glass cube which has an outer cube surrounding it of stainless screen(with voids). The distance between the inner and outer cube is 3 meters. While looking at the radiance images from an inside of the glass cube (camera view), I see bands of white light at the edges of the glass cube. Could someone explain why this is occuring?

Thanks,
Pri
