Hi!
I trying to compare the results that I get from a Honeybee radiation simulation with another algorithm and for that I want to first exclude all reflections.
I set the material reflectances to 0 and used 0 ambient bounces for the calculation. However the 0 ambient bounces seem to be giving me 0 cumulative radiation values. I would expect that I would still get the values for direct and sky diffuse radiation. Can someone explain to me why this happens?
If I am not wrong, Honeybee is using RADIANCE’s rtrace function for this calculation, and at the function description I see that an ab value of zero implies no indirect calculation.
(http://radsite.lbl.gov/radiance/rtrace.1.html). But shouldn’t I still get the direct component?Radiation_HB.gh (64.5 KB)
