My chosen textures and their locations can be seen in Fig.07 & Fig.08.
At the post-processing stage I added detail to the scene by working with texture, color correction and lighting effects. This was the first output render (Fig.09).
It was most convenient to make adjustments to the color by using Adjustments Layers (Layers > New Adjustment Layer). After with the Color Balance, Levels and Selective Color options, I ended up with the following image (Fig.10).
Fig.11 shows the image after I added lighting effects.
Now it was time to add some rust, damage and general wear and tear to the scene to give it the old, dilapidated feel that I was after. I found suitable textures for this on the V19 - Total Textures "Destroyed & Damaged" DVD (Fig.12).
I started by adding some detail to the wall (layer type: Overlay) (Fig.13 - Fig.15).
