Interior Mapping demo

[Grall]

How does the pixel shader identify a window to insert the cube map into, if the building is one solid polygon face...?

There´s probably a monochromatic alpha-mask selectively showing either the static facede texture, and the angle-based-scrolling interiors texture.

SimCity had a version of interior mapping as well.
