The Woodgrain procedural texture produces a wood grain type pattern (figure 1).

Woodgrain Parameters

Light Wood - The light wood color. 

Dark Wood - The dark wood color. 

Sharpness - The ring to grain ratio, larger values will smooth the grain lines. 

Ring Intensity - Determines the intensity of the growth rings providing more contrast between growth rings with higher values. 

Ring Frequency - Specifies the number of growth rings. 

Ring Unevenness - Adds variation to the spacing of the growth rings.

Ring Noise - Determines the intensity of the ring noise by roughing the edges of each ring. 

Ring Noise Frequency - Alters the waviness of the growth rings the father this value is from 0. 

Graininess - Determines the intensity of the wood grain. 

Grain Frequency - Specifies the number of grain lines. 

Trunk Wobble - The intensity of the noise factor for both the grain and rings. Values farther from 0 will produce more circular results. 

Trunk Wobble Frequency - Values farther from 0 will tend to scale or repeat the effect. 

Angular Wobble - The intensity of the angular noise factor for both the rings and the grain. 

Angular Wobble Frequency - The frequency of the angular wobble. 

Transform Pin - Positions, scales, and rotates the surface texture.

Projection Pin - Sets how the texture projects onto the surface.
