Hi, Alejandro,

Google "radiance photon mapping" tells us the following link:
http://www.ise.fraunhofer.de/en/admin-folder/archiv/applied-optics-and-functional-surfaces-draft/lighting-technology/lighting-simulations/light-directing-with-radiance-photon-mapping/download-photon_mapping/download-photon-mapping

My typical process is to export to .obj, then use the command obj2rad. When you export to obj, be sure to tick the box to export materials, so that any material names you've assigned in Rhino carry over into the rad files. Also, the -f option for obj2rad tends to keep each surface contiguous (rather than triangulating further than the obj export).

Have you tried the open source project in grasshopper called Ladybug?

Thank you Chien Si for mentioning Ladybug.

Alejandro, You can use Honeybee which is a part of Ladybug plugin (
Ladybug Tools - Grasshopper) to prepare the geometry and
write the files (sky files, rad files for the geometry and materials).
There are components to create the materials and assign them to the
geometry.

I haven't announced the release for Honeybee yet but you can download it
form the github repository: GitHub - ladybug-tools/honeybee-legacy: 🐝 Honeybee is a free and open source plugin to connect Grasshopper3D to EnergyPlus, Radiance, Daysim and OpenStudio for building energy and daylighting simulation

Currently you can run rtrace and rpict lines from the runDaylightAnalysis
components. The project is open source though and you can modify the code
to suite the purpose of your study or you can develop a new component to
run forward raytracing simulations from Honeybee/Ladybug. The latter sounds
perfect to me! ;).

I can send you an example file if that helps.

Cheers,
Mostapha
