In SketchUp - Windows are recognized as glass materials (less than 100% Opacity).
In Revit - Windows are recognized as glass materials (less than 100% Opacity).
In Rhino - While windows are recognized as glass materials in SketchUp and Revit, in Rhino you must put all of your glazing and/or skylights on a layer and color the layer opaque blue (RGB(0,0,255)) in order for it to be recognized in LightStanza. LightStanza sets all polygons inside of layers that are set to blue to glass, so make sure you remove any extra blue materials that you would not like to be uploaded as a window or skylight.
* If you plan on having different materials for different window sets in LightStanza, you can apply different hues of blue (RGB(0,0,1-255)) to different window groups in Rhino. For example, if 20 of my windows are going to be daylight redirection film, and 20 of my windows are going to be dynamic glass, I could apply RGB(0,0,254) to the 20 double pane glass windows, and RGB(0,0,253) to the 20 dynamic glass windows. Once I upload this LightStanza, I can change all of my same-color windows to a new material at once.
