Color
Colorizes the ring and grain function. Experimentation is required to fully understand and use this
control.
Ring Intensity
Reduces or increases the prominence of the annual rings. While the parameter can go negative, its
useful values are between 50% and 150%.
Ring Scale
Scales the rings of the wood before being stirred by the turbulence function.
Ring Turbulence, Turbulence Scale
Stirs the annual rings so they may have a more natural look. Turbulence Scale simply scales the noise
used for the ring turbulence.
Ring Variance
Varies the width of the rings without changing their respective positions.
Core Variance
Disturbs the origin of the rings so it looks as if the tree the wood came from did not grow perfectly
straight.
