BSDF from Glazing System with Frit Shade Layer

[Clarence Somerset]

Hello,

I built a glazing system consisting the following:

1. Shade 1: A frit that I imported from an XML file. The XML had been constructed by running genBSDF on 2 .rad files for visible and solar, and then combining/editing them manually

2. Air gap of nominal 0.01mm

3. Laminate

4. Argon

5. Laminate

My goal is to import this glazing system into Rhino/Grasshopper to run glare analysis via Radiance. To that end, I exported a BSDF .xml for the glazing system. However, the resulting .xml is very small (5kb) and does not contain any wavelength data. Radiance is thus unable to generate a rad material from this file.

Is the absence of wavelength  to be expected or is there something wrong upstream that resulted in a total absence of wavelength data? Thanks!
