Made the trim for my building today. I think I'm going to have these lay out around my whole level. The bottom ones use a texture I made from a picture of a more worn building I found.
The reason for this is because I wanted more dirt and grunge around the base of the buildings to fit in with the worn and damaged look of the rooftop.
Just the diffuse and spec so far. I will be making the normals to bring out the smaller details.
