3D Workshop - Textured Metal Shaders For Industrial Design adding loop cuts we can pick out layout areas which will receive different textures. With some push and pulling you can quickly create some nice looking and comfortable to wear ring designs. (Image 25) Time to create the materials. A
- channel two : inverted displacement texture - channel three : color texture for darkened silver
We already created the material index for the ring. Switch to the Material window (F5) select the first material which represents the majority of the unstructured ring inside the Links and Pipeline tap. Rename that material to something meaningful, like "Main body". Set the Object color to black. To rebuild a perfectly polished silver surface, turn on Ray Mirror, set the RayMir value to 1.00 and create a sharp specular highlight with the Blinn shader.
- Detail mesh faces: structured material with additional silver settings
Even perfectly polished surfaces often still have some fine grooves and scratches. Through buffing you smooth out the sharp edges of those scratches and those produce a more even reflection which gives you the impression of a scratch free surface. An easy step to create that effect is to quickly unwrap the faces of the main body. Apply two loop edge seams along which Blender will cut the ring apart. (Image 26)
- channel one : displacement texture
Switch to the Texture window (F6) and create voronoi texture. You can

scale it down a little bit and activate the Colorband option under the Colors tap. What we want is a bump map which only has few scratches here and there. For that set the black color Alpha value to 1.00 and turn cyan into pure white. We still have that cell structure grain typical for voronoi. Move the black color two thirds to the right side and the white color to the full left side. Know we have a nice black surface with some dots only. It might make sense to rename that texture something like "Voronoi Scratch". See Image 27. Switch back to the Material Window (F5) and apply the newly create texture inside the 'Map To' tap only to the Nor channel and give it a very low Nor value. Inside the 'Map Input'
