Hopefully I’m just missing something very simple with this one. I’ve been working on my model for my thesis, and after putting a simple glass material on the window panes, I’ve realized that the GI doesn’t penetrate the glass. It still renders the glass as transparent, but it doesn’t show the rays coming through the glass. Am I missing some simple option here?
The SketchUp viewport shows light coming through the panes as seen in the first image, they just don’t show up in the render.
