The specular map was used to show a worn surface where the paint has been eroded but I also used a worn version of the circular hatch and changed the colour to help compliment the scene. You can see the final version of the scene here in Fig.24 compared to the clean version (Fig.25)..
Adding Wear and Tear - Hospital Scene:
1. This is certainly the simplest of the three scenes but the one in which the most wear and tear can be observed. The reason why this shows the greatest contrast is that the initial version was very clinical and polished and represented an environment that reflects hygiene. In order to really degrade the scene I incorporated a number of dirt maps from V5 of the Total Textures collection. In Fig.26 you can see the original texture on the far left with the render below and then on the right is the neglected version using the two dirt maps in the center of the image. I've altered the colour of the ceiling panels somewhat to fit with the scene but you can see how effective the dirt maps have been when you compare the final renders underneath. This has essentially been the work pattern used throughout the scene - selecting dirt masks and overlaying them in a seperate layer set to multiply and with the opacity turned down slightly. You could also use these as masks to control the mixing of two materials using a Blend material. In this case you would have the ceiling texture that exists and a dirt layer and the mask would be used to control the visibilty of each.
This image was created using a few of the hundreds of textures from the Total Texture CDs - very comprehensive texture collections priced with the hobbyist in mind. To see more examples, download free
