Skins Series - GrainyWood
This component creates a very grainy wood pattern. The depth of the grain can be varied along with the wood ring spacing.

Tweak Link User Parameter Name Function
Function Parameters
  User Seed This parameter controls the seed for the whole pattern. By changing its value different patterns can be created.
Ringiness This parameter controls the ring pattern in the wood. The larger the values the higher the frequency of the rings.
Grain Frequency This parameter controls the frequency of the wood grain. The smaller this value the smaller the grain.
Graininess This parameter controls the grain intensity. The larger this value the more pronounced the grain pattern.
Common Parameters
  Noise Magnitude
The Noise Magnitude controls the size of the Turbulence that is used to "stir" up the texture. As the Magnitude value is increased the amount by which the pattern is disturbed is increased.
  Noise Scale
The Noise Scale parameter controls the frequency of the turbulence, that is the periodic frequency. When the scale is at a high value the turbulence will be tight and crinkled and will become increasingly smoother as this parameter is decreased.
  Noise Octaves
The Noise Octaves parameter controls the number of times noise is summed in order to generate the turbulence. Turbulence is generated by summing noise with each summed noise being half the magnitude of the previously summed noise. The number of times the noise is summed is determined by octaves. So, at low values the turbulence will be smoother and will increase in detail (due to the fact that the summed noise is getting smaller) as the number of octaves is increased. All this basically means is that the turbulence becomes more "crinkled" as the number of octaves is increased.
Noise Omega
The Noise Omega parameter controls the granularity of the turbulence and is only used when it is non-zero. The higher the value the more granular the turbulence.
  Noise Velocity
The Noise Advection parameter controls the speed of the noise over the whole animation cycle. Basically, the higher this value the more active the noise is.
Noise Time
The flow noise can be animated by morphing the Time parameter.
Brightness
This parameter controls the overall brightness of the pattern in much the same way as the brightness control on a television.
  Contrast
This parameter controls the overall contrast of the pattern in much the same way as the contrast control on a television.
Lower Clip This parameter sets the lower limit for the actual texture function. This allows the function to be clipped or parts of it expanded.
Upper Clip This parameter sets the upper limit for the actual texture function. This allows the function to be clipped or parts of it expanded.
  Blend Function This link only parameter controls the blend function used by the texture. By linking it to say a generator the profile of the blend can be altered.
Color Only Parameters
Low Color This parameter sets the start color for the texture pattern.
Grain Color This parameter sets the grain color for the texture pattern.
Percentage Only Parameters
Low Percentage This parameter sets the start percentage for the texture pattern.
Grain Percentage This parameter sets the grain percentage for the texture pattern.
Bump Only Parameters
Low Bump This parameter sets the start bump height for the texture pattern.
Grain Bump This parameter sets the grain bump height for the texture pattern.
Bump Scale This parameter controls the overall scaling of the bump height. When it is positive it controls the height of the bumps and when negative it controls the depth of the pits.

Tweak This means the parameter can be tweaked.
Link This means the parameter can be linked.
User This means the parameter can be controlled by the user.
