60 2 <strong>Architectural</strong> MaterialEach have advantages <strong>and</strong> disadvantages, but the one we will try here is the last one. Thereason for choosing this method is that it works well together with interpolation.1. Create a map for the “brush streaks”. There are many ways to do this, either by paintinga map in a paint program, or by using a “Noise” map that has been stretched heavilyin one direction.2. The map should vary between middle-g<strong>ray</strong> <strong>and</strong> white. Apply this map to the refl colorin a scale suitable for the brushing.3. Set diffuse to white (or the color of the metal) but set diffuse weight to 0.0 (or a smallvalue).4. Make sure refl is metal is enabled.5. Set refl gloss to 0.75.6. Set anisotropy to 0.1 or similar. Use anisotropy rotation to align the highlightproperly with the map. If necessary use anisotropy channel to base it on the sametexture space as the map.Brushed Metal
