This also means that you can now see through the windows of your Honeybee models visualized with the HB Visualize by Type component:

This is great, thanks chris! My suggestion is to also do this with AirBoundary faces

Also, I noticed that HB Visualize by Because now also makes the outdoors boundary condition transparent. I don’t know if this is intended behavior?
