Hi everyone!  
I’m working on a glare analysis using Honeybee for a glazed pedestrian bridge in Oslo. The bridge has transparent walls and a translucent glass floor, while the roof is opaque.

I’ve created different HB Glass Modifiers to simulate various glazing types:

- Clear glass
- Silk-screened glass
- Triple Low-E glass with Argon

Each modifier has different solar and visible transmittance values, and I correctly assigned them to the bridge surfaces using `HB Face` and `HB Model`. However, when I run the Annual Glare Analysis with `HB Annual Glare`, the final results seem to be identical across all glazing types. There’s no variation in the glare percentage or spatial distribution, even when I completely change the material properties.

I’ve double-checked:

- The modifiers are connected to the correct surfaces.
- The geometry is accurate and facing correctly.
- I’m using a proper EPW file for Oslo.
- The model runs without errors.

But still, the output stays the same.  
Could it be that the HB Glass Modifier is not affecting the glare results properly? Or am I missing a step in assigning/translating the glass material for glare simulations?

Thanks in advance for your help!
