Blender 3D: Noob to Pro/Every Material Known to Man/Rubber

Rubber

Method 1

This method is for a general, computer-performance-oriented rubber material.
Color

• Col: (Adjust as needed)
  
  • R - 0.15
    
  • G - 0.14
    
  • B - 0.12
    

• Spec: (Change as needed)
  
  • R - 1
    
  • G - 1
    
  • B - 1
    

Shaders

• Diffuse Shader:(Minnaert)
  
  • Ref - 0.7
    
  • Dark - 0.6
    

• Specular Shader:(Blinn)
  
  • Spec - 1.5
    
  • Hard - 10
    
  • Refr - 2
    

Some people think it looks TOO smooth. If you feel that way, add a very light texture:
Texture
Tex Type - Stucci

• StucciType - Wall In
  
• NoiseType - Hard Noise
  
• NoiseSize - 0.05
  
• Turbulance - 3F
  
• Noise Basis - Voronoi F1
  

Map Input

• Coordinates - Orco
  
• SurfaceType - Cube
  

Map To

• MapType - Nor
  
  • NorSlider - 0.3
    

Method 2, w/SSS

This method is a better quality and more realistic Rubber material, but works best using SubSurface Scattering, so it may affect the time of your Render.
