Noise Map

The Noise map creates random perturbation of a surface based on the interaction of two colors or materials.

Noise map used for the edges of the street

Procedures

To change a component color:

In the Noise Parameters rollout, click a color swatch to display the Color Selector.
Adjust the color.
Click OK to dismiss the dialog.

To use a map for a component:

In the Noise Parameters rollout, click a map button to assign a map to a color.
Alternatively, use the Slate Material Editor to wire a map to the Color 1 or Color 2 component.

To swap the two component colors:

In the Noise Parameters rollout, click Swap.

To adjust mapping coordinates:

In the Coordinates rollout, adjust Offset, Tiling, or Angle.

Interface

Note: For the Noise map, the tiling and mirroring controls are disabled in the Texture Tiling And Output rollout.

Noise Type

Regular (The default.) Generates plain noise. Basically the same as fractal noise with the 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 the fractal noise.
Turbulence Generates fractal noise with an absolute value function applied to it to make fault lines.

Regular, Fractal, Turbulence

Size

Sets the scale of the noise function, in 3ds Max units. Default=25.0.

Noise Threshold

When the noise value is above the Low threshold and below the High threshold, the dynamic range is stretched to fill 0 to 1. This creates a smaller discontinuity (technically, 1st order instead of 0 order) at the threshold transition and produces less potential aliasing.

High Sets the high threshold. Default=1.0.
Low Sets the low threshold. Default=0.0.

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=3.0.

Phase

Controls the speed of the animation of the noise function. Use this option to animate the noise function. Default=0.0.

Swap

Switches the position of the two colors or maps.

Color # 1 and Color # 2

Display the Color Selector so you can choose one or the other of the two principal noise colors. Intermediate color values are generated from the two colors you select.

Maps

Select the bitmaps or procedural maps to appear in one or the other noise color.

Turn on the checkboxes to make the maps active.
