I was reading this tutorial, in section 3.2, to calculate the contribution of the ground material to the lighting in the scene, Axel assigned a light source to the ground material by using “-m”. I need to assess the contribution of different patches of a highly reflective tower facade to the lighting in a scene inside a room across the tower. After reading Axel’s tutorial I’m kind of convinced that this can be accomplished by splitting the tower facade into smaller surfaces(patches) then assigning them as light sources. Radiance experts please correct me if I’m wrong.
Is it possible to assign a light source to a surface in Honeybee [+]? Currently, all light sources in HB[+] are sky matrices, unless I’m missing something.
Update: if this is not possible in HB[+], can I get the desired results by adding the patch’s material name preceded by -m, for example, patch1’s material is called ref_glass_1, so I can simply add
**"-m ref_glass_1"** to the end of the rcontrib line, am I right?
