This node creates controlled random variations. The variation source can be attribute or primvar based. @parameters
inputRGB: The color that you would like to vary.
varySource: The source of the variation. For user attributes, type user:myattribute.
varName: If varySource is 1 or 2, the name of the primvar or user attribute.
varType: The type of the primvar or user attribute used to seed variation. If using a primvar, it should be either uniform or constant : per-vertex/face primvars are not supported.
hue: Limit random hue shift. Ranges from 0 (no variation) to 1 (full variation).
saturation: Limit random saturation scale. Ranges from 0 (no variation) to 1 (full variation).
luminance: Limit random luminance scale. Ranges from 0 (no variation) to 1 (full variation).
gamma: Limit random gamma variation. Ranges from 0 (no variation) to 1 (full variation).
probability: Range from 0 to 1 specifies the possibility of applying the variation.
hueMode: Centered: The amount of variation will be centered around the current value.
saturationMode: Centered: The amount of variation will be centered around the current value.
luminanceMode: Centered: The amount of variation will be centered around the current value.
gammaMode: Centered: The amount of variation will be centered around the current value.
verbosity: Diagnostic output levels for scene debugging.
