2. This same procedure is followed when altering all the other main components including the ceiling panels, walls and pipe supports; a comparison of which we can see in Fig.21. Apart from the darker tones the two are very similar except perhaps for the panel in the top right which has been replaced by a more worn version on the CD. Similar to the floor texture you can see in the final renders on the right that the specular map also makes a big difference to the finished look. In the case of something like the pipework it is also a combination of both the colour and specular maps that give us the look we are after (Fig.22). You can see in the top half of the picture that most of the pipe itself reflects the light due to the higher quantity of white in the specular map. In the more worn version the specular map corresponds quite closely to the colour map and only creates highlights along the weld lines.
3. The last important component in the scene that is perhaps the focul point is the doorway at the end of the corridor which in the worn version is no longer red but more significantly has utilised a specular map which I extracted from Total Textures V5 - Dirt masks and Graffitti (seen on the left in Fig.23).
