File	Brushed Metal By darek 4

One of the most-requested materials for blender is brushed metal. So, here it is!

Create a New Material

1. Select your object with RMB.
2. Go to the Material Buttons(F5).
3. Add New Material.
   
4. Set the Color of the material to a dark gray.
   
5. Copy the Shader settings below. Spec and Hard control the highlights. Ref is reflectivity, in practice it make the material lighter or darker. Tangent V
   is where the magic happens. If this button is pressed, blender
   stretches the highlights of an object along its tangent. Exactly what
   we need for a brushed metal surface.
   
6. Turn on Ray Mirror. Set RayMir to 0.2. This makes our metal reflective.
   
   Your material should look like this by now:
   
7. Now Add New texture.
   
8. Go to the Texture Buttons(F6).
9. Set Texture Type to Clouds.
   
10. Turn on Hard Noise. Set NoiseSize to 0.3.
    
11. Go back to Material Buttons(F5).
12. In the Map Input tab, turn on Sphe. Set SizeY to 75. This is how we get the horizontal grooves.
    
13. In the Map to tab, turn on Col and Nor. Make the Color to a medium gray. Set Nor to 0.2.
    
14. Render! F12

Note
that results vary greatly depending on what type of lighting is used.
Lights with Ray Shadow on tend to cause ugly jagged edges.

Hope this is useful.
