1. This is a real fun part of the texturing phase - applying dirt to age the textures and give the scenes a sense of neglect and thus providing a weathered look. In the case of our Sci-Fi version I decided to give the whole scene a darker look overall and lessen the variation in the textures so as to create a grime ridden appearance and also emphasize the lights. The first step is to replace the floor textures with dirtier versions from the same CD collection on V7 and then go into Image - Adjustments - Colour Range and use a colour picker to select an area of darker pixels on the image as seen in the image below. With this selection group done feather it by 1 or 2 pixels to soften it slightly and then use the colour dodge tool to lighten certain areas where you would expect to see a tarnished and worn look, eg. around the grooves. You can see in the image below, I have concentrated this method around the joints to create the specular map (a simple duplicate converted to greyscale - top left) You can add further wear following the same process again but by altering the fuzziness slider and choosing different coloured pixels.
When we apply our new textures we can see how the changes affect the look of our floor in the image below. On the right are the corresponding specular maps with increased contrast on the top version to accentuate the feeling of ageing etc.
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 the image below.
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.
