UV Maps ( only on the parts where I used textures the rest of the scene is hypershade)
Unfortunately, due to the complexity of my final scene and too much of the geometry in the buildings I wasn't able to make wireframe of any of the buildings. I managed to make wireframe only of the surface.
Here are at least snapshots of the wireframe mode.
I tried to get rid of the unnecessary geometry of the buildings themselves and mostly duplicate them as 'instance' but it was still too complex and too much of the geometry that maya refused to process. Not even rendering from the render layers didn't help.
