Type Creates random perturbation of a surface based on the interaction of
two colors.
■ Regular. Generates plain noise. Basically the same as fractal noise with
levels setting at 1. When the noise type is set to Regular, the Levels spinner
is inactive (because Regular is not a fractal function).
■ Fractal. Generates noise using a fractal algorithm. The Levels option sets
the number of iterations for fractal noise.
■ Turbulence. Generates fractal noise with an absolute value function applied
to it to make fault lines. Note that the noise amount must be greater than
0 to see any effects of turbulence.
Size Sets the scale of the noise function. Smaller values give smaller chunks
of noise.
Color 1 Provides the option of selecting a color for one of the components.
Click the color box to display the Select Color dialog box.
Color 2 Provides the option of selecting a color for the component.
Click the color box to display the Select Color dialog box.
Low Threshold Specifies the low noise threshold. Range = 0 to 1; Default =
0.
High Threshold Specifies the high noise threshold. Range = 0 to 1; Default =
1.
Levels Determines how much fractal energy is used for the Fractal and
Turbulence noise functions. You can set the exact amount of turbulence you
want and also animate the number of fractal levels. Default = 3.
Phase Controls the appearance of the noise. Use this option to vary the
appearances of different objects that use the noise map.
UVW Offset Moves the starting point of the map along the UVW axes.
UVW Tiling Adjusts the tiling of the map along the UVW axes.
