Can i read the different contributions (direct, indirect specular, indirect diffuse) that sum up to the illuminance (lux) of a point?

Radiance via Honeybee, trying to see which parts of the calculation contributed most to the overall illuminance of a point. Is there a results viewer program for Radiance output of that sort?

The short answer is 'no.' With multiple reflections, there is not just diffuse and specular, but diffuse to specular, and specular to diffuse, and diffuse to specular to diffuse, ad infinitum. You can't really separate these things to report them.

Thank you Greg, it makes sense that they are inseparable. So then if one needs to test whether a "mirror" material has been modeled appropriately (the mirror actually contributing on the illumination of a sensor point, is there a good practice methodology to be followed by use of the rendering settings?
