How to add a glass radiance modifier to a HB aperture created by ratio

How do I add a HB Glass radiance modifier to a HB Aperture that is created by ratio on the solid face? Please see the screenshot attached.

Hi @deepthi.ravi there is a component called HB Apply Window Modifier in 1::Modifiers which will allow you to add the modifier after the apertures by ratio component.


I hope that helps

I have a follow-up question on this.

In the case where a glass/window construction or window modifier is not applied, what does the model assume as the U-value, Transmissivity, G value, etc? Where can I find that information on its inbuilt assumptions on the glass made by the ‘apertures by ratio’?

@deepthi.ravi here is a scene breaking down the default window construction set


the E+ object text from the window:
