Border Shading some windows missing

Hello,
I am having trouble getting Border Shading to apply on each window. I have tried a few configurations but none of them give me border shades on each of the windows, there doesn’t, to me, seem to be a pattern in which windows receive them either.
Greatly appreciate any assistance! I have attached some images including one of the room configuration if this is helpful.
Thank you,
Dan

Hi @dbishop,

The first thing that comes to mind is the direction of the surfaces - I’d guess the shades are being produced but are going into the building as the surface normal of the original window is facing in.

The simplest thing to do would be to Flip the surfaces in Rhino.

Excellent - thank you! That did it.
