dear all
hello, do you know what causes the my radiance analysis show illumination
higher than 50 lux when I simulate a night time,although in the analysis
process it is written that warning no light source found? i have a zone
with a window in the south wall, with no electrical light.materials are
plastic
thank you

Hi Shailan!

hello, do you know what causes the my radiance analysis show illumination higher than 50 lux when I simulate a night time,although in the analysis process it is written that warning no light source found?

Did you define any sources? The warning is just about sources of type "light". Do you have sources of type "glow" in your scene? If you have no sources, what would you analyze?

Cheers, Lars.

Also to consider would be what ambient value (-av) you are setting....

Dear Jack and Lars
thank you for your quick answer. i don't intend to analyse night time. but
i set the time of my analyse in the ecotect for 1am by accident, i should
mention that i draw my model in the ecotect and then export it to radiance.
i saw in my render that the illumination is like that it is morning. so as
i understood from what you told, it is not a problem from my modelling.am I
right?
