[Radiance-general] HIgh illuminance values.

[G V DEEPAK]

Thanks Mr Gulielmetti,

Yes its for single time and sun angle , we were trying sample 
simulations for 10, 11 am and 12 noon. I am getting these weird 
results. I have checked the geometry a number of times as well as 
all the parameters, these results seem very strange. any 
particular reason..?

Thank you
