Shared 3D texture attributes
 
                
               
             
             
            
            Wood
          
       
       
       
       
      
      Simulates wood by projecting a 2D pattern.
         This pattern consists of concentric ring layers defined by veins
         and filler. When you map the Wood texture to
         a surface, the surface seems to be carved out of wood. When you
         map it to several surfaces, they seem to be carved from a single
         block of wood.
      
      Find this texture in the 
                  Create bar.
         To apply this texture as a texture map, see 
                  Map a 2D or 3D texture.
      
      Tip
            
               - There
                  are four Wood attributes that are frame
                  constant, meaning that mapping them with textures or other nodes
                  that produce different values from point to point may lead to unpredictable
                  results. These attributes are: Grain Spacing, Layer
                     Size, Randomness, and Age.
                  You can key all of these attributes to make their appearance change
                  over time in an animation sequence.
               
- If
                  you use the Wood texture as a bump map,
                  lower the Grain Contrast setting to reduce
                  the potential for texture artifacts during animation.
               
 
      
         - Filler Color
- 
            
               The
                  color of the space between veins. The vein color diffuses into the
                  filler color. Double-click the color bar to choose a different color
                  from the Color Chooser.
                
 
- Vein Color
- 
            
               The
                  vein color of the wood. The vein color diffuses into the filler
                  color. Double-click the color bar to choose a different color from
                  the Color Chooser.
                
 
- Vein Spread
- 
            
               The amount of vein color that diffuses
                  into the filler color. The valid range is 0 to infinity. The slider
                  range is 0 to 3. The default is 0.25.
                
 
- Layer Size
- 
            
               The average thickness of each layer or
                  ring. The valid range is 0 to infinity. The slider range is 0 to
                  0.5. The default is 0.02. (The thickness of individual layers or
                  rings is also influenced by the Randomness and Age values.)
                
 
- Randomness
- 
            
               Randomizes
                  the thickness of individual layers or rings. The range is 0 to 1.
                  The default is 0.5.
                
 
- Age
- 
            
               The
                  age of the wood (in years). This value determines the total number
                  of layers or rings in the texture, and influences the relative thickness of
                  central and outer layers. The valid range is 0 to infinity. The
                  slider range is 0 to 100. The default is 20.
                
 
- Grain Color
- 
            
               The color of the random grain in the
                  wood.
                
 
- Grain Contrast
- 
            
               Controls
                  the amount of Grain Color that diffuses into
                  the surrounding wood color. The range is 0 to 1. The default value
                  is 1.
                
 
- Grain Spacing
- 
            
               The average distance between grain
                  spots. The range is 0.002 to 0.1. The default value is 0.01.
                
 
- Center
- 
            
               The
                  location of the center of the texture’s concentric rings in the
                  U and V directions. The range is -1 to 2. The default values are
                  0.5 and -0.5.
                TipDo not set the Center values
                     less than -3 or greater than 3.
                   
 
Noise Attributes (Wood)
         
         The Wood texture
            creates a 3D texture by projecting a 2D pattern. The Noise Attributes control
            the randomization (using fractal noise) of the texture in the direction
            the pattern is projected. Select from the following:
         
         
            - Amplitude X, Amplitude
                     Y
- 
               
                  An
                     average scaling factor applied to all values in the fractal noise
                     in the texture’s X and Y directions. The valid range is 0 to infinity.
                     The range is 0 (no noise) to 1 (strong noise). The default value
                     is 0.1.
                   TipThe Wood texture
                        renders faster if the Amplitude X and Amplitude
                           Y values are both 0. 
                      
 
- Ratio
- 
               
                  Controls
                     the fractal noise frequency. The range is 0 (low frequency) to 1
                     (high frequency). The default is 0.35.
                   
 
- Ripples
- 
               
                  Determines
                     the texture’s waviness in the X, Y, and Z directions. The values
                     represent the frequency scale of the fractal used to generate the
                     texture. The range is 0 to 20. The default is 1.
                   
 
- Depth
- 
               
                  The minimum and maximum number of iterations
                     used to calculate the texture pattern. This parameter controls how
                     fine grained the texture is. The range is 0 to 25. The default values
                     are 0 and 20.
