Solid Fractal

Represents a 3D random function with a particular frequency distribution (fractal).

Find this texture in the Create bar. To apply this texture as a texture map, see Map a 2D or 3D texture.

TipAssign this texture to the material’s bump map to achieve a coarser simulated texture.

Threshold: Offset factor applied to all values in the texture. The valid range is 0 to infinity. The slider range is 0 to 1. The default is 0.
Amplitude: Scaling factor applied to all values in the texture. The valid range is 0 to infinity. The slider range is 0 (no noise) to 1 (strong noise). The default is 1.
Ratio: Controls the frequency of the fractal noise. The range is 0 (low frequency) to 1 (high frequency). The default is 0.707.
Frequency Ratio: Determines the relative spacial scale of noise frequencies. If not a whole number, the fractal does not repeat at the UV boundaries. For instance, a cylinder with default placement would display a seam.
Ripples: Determines the texture’s waviness in the X, Y, and Z directions. The values represent the frequency scale of the fractal used to generate the texture. The range is 0 to infinity. The default is 1.
Depth: The minimum and maximum number of iterations used to calculate the texture pattern. This parameter controls how fine grained the texture is. The range is 0 to 20.

NoteThe following attributes let you swirl the noise pattern in a Solid Fractal texture to create interesting effects.

Bias

Attracts the -1 to 1 noise towards either 1 or 0. Values greater than zero result in a more contrasting fractal while values less than zero make it more flat and spiky.

Inflection: Applies a kink in the noise function. This can be useful when creating puffy or bumpy effects. Inflection is off by default.
Animated: Turn on to access the Time and Time Ratio attributes (see next).

Time: Determines the relative time scale of noise frequencies. If not a whole number, the animation does not repeat when Time = 1.
Time Ratio: Default is equal to the Frequency Ratio setting, which means higher frequency noises move faster in direct proportion to the frequency. For example, to create more natural-looking effects, such as water waves, if the Frequency Ratio is 2, set the Time Ratio to 1.4.
