[Radiance-general] Re: Radmap irradiance shifts

[Christopher Rush]

I have noticed that, actually I've noticed it with a custom script that
sums up CIE sunny skies, in a cumulative file, then renders irradiance
for a scene looking at direct only sun (ab 0). In my case I was looking
at an exterior aerial veiw of one building facade sited amongst other
buildings. The odd irradiance seems to occur on one of the neighboring
buildings that extends higher than all the others.

Hello All, 

Was wondering if others have noticed horizontal bands of lower
irradiance values across the top 1/3 of the images produced from Radmap?
These shifts look like strong shadow lines but don't relate to any
occluding geometry in the scene.  We seem to get these artifacts when
using exterior views looking down onto the scene and using any number of
weather files.

Thanks,
Chris H
