31. Add a Vector Math node (press Shift + A and navigate to Converter | Vector Math)
and set Operation to Average. Connect the Normal output of the Bump_Windows
node inside the WINDOWS frame to the first Vector input socket, and the Normal
output of the Bump_Hull node inside the HULL frame to the second Vector input
socket. Then connect the Normal output of the Average Bump_Hull node to the
Normal input sockets of the Diffuse BSDF, Glossy BSDF, and Anisotropic BSDF
shader nodes, as shown in this screenshot:

The steps to create the location mask for the windows are as follows:
32. Add one more Mapping node (press Shift + A and navigate to Vector | Mapping)
and four Checker Texture nodes (press Shift + A and navigate to Texture | Checker
Texture). Connect the Texture Coordinate node and the nodes as usual. Then label
them as Mapping6_Mask , Checker Texture1_Mask , Checker Texture2_Mask ,
Checker Texture3_Mask , and Checker Texture4_Mask . In all, the four Checker
Texture nodes change Color2 to pure black.
33. Add a MixRGB node (press Shift + A and navigate to Color | MixRGB), set Blend
Type to Screen and Fac value to 1.000 , and label it as Screen_Mask . Connect the
Color output of the Checker Texture1_Mask node to the Color1 input socket of the
Screen_Mask node, and the Color output of the Checker Texture2_Mask node to
the Color2 input socket.
