Hello,

I am trying to assign a custom Radiance material to quickly simulate frit with HB+ annual daylight recipe. I’m getting an error when starting the simulation.

What is the easiest way to apply this radiance material? I’ve tried directly as a text panel but it seems to not be supported? I’ve tried applying this modifier to a HB face and HB aperture and get an error either way.

Hi @rxs5160,

This should still work. You can add glazing_material and frit_material as the dependent modifiers.

Funny enough, that is what I used to create that material! Thanks for the handy python script.
I did check that perforate.cal is located in C:\Radiance\lib

I’m getting this error:

Can you share a sample file with internalized geometry either here or in a private message?

attached is a simplified version with internalized geometry. model is in meters
customfritRAD.gh (124.0 KB)

I should note I am working in Rhino8 but not sure that will make a difference for this issue.

Try to put the cal file in C:\Program Files\ladybug_tools\radiance\lib as well. This should solve it.
