Modified mirror with fresnel reflection

grasshopper honeybee

I’m trying to assign this modified material in Honeybee Radiance 1.10. to simulate specular reflections from a glazing unit. Couldn’t figure out how to use the “modifier” components to do this. @mikkel is this something possible to do?

void trans glz_solar_alt
0
0
7 0.585202 0.585202 0.585202 0.554 0 1 1

void brightfunc glz_rfsol_front_pat
2 Rfsol_front c:\radiance\helpers\rfsol_front.cal
0
0

glz_rfsol_front_pat mirror glz_solar_front
1 glz_solar_alt
0
3 1 1 1

I thought maybe this works but the mixfunc script didn’t help.

I was also looking at trying to modify the material in the folder structure manually before radiance runs, but in the new honeybee seems like I can’t do that. is there is no way to write the simulation without running as well?

Hi @mr,

There is a chance that this much simpler method will work, however, I have not tested it in a recipe. If Radiance cannot find rfsol_front.cal you can try to place it in c:\radiance\lib.

Thanks, Mikkel!! That worked.
