Can we run radiance analysis with only reflection?

Hello,

I wonder if it was possible to launch an analysis with radiance on the analysis of the reflections, a topic has already been opened on this subject.

How to run radiance analysis only for facade reflection

Hi, everyone, I am trying to analyze a concave facade to see if there’s too much reflection on one spot. When I was doing research I found one paper mentioned there’s some radiance simulation method to run rtrace for forward ray racing and Rtcontrib to quantify the reflected daylight. Since ladybug and honeybee are open source I feel like I can modify the code to run those analysis but couldn’t locate the exact line of code to do the modification. Anyone can help? I have got the target area th…

I would like to do an analysis with single, double, triple, quadruple superpositions of reflections and output a false color image.

Well… i’ve tried the mostapha solution, but “pcomb” doesn’t work on my desktop, it just loopback and tried to create the difference between my two images…
