Properties

 

 

Property

Description

Size

Sets the width and height of an imaginary camera observing the texture.  Increasing these values is like moving the camera farther away from the texture.  To create low-frequency patterns, enter values between 0 and 1.

Location

Sets the X and Y coordinates of an imaginary camera observing the texture.  Changing these values is equivalent to translating the texture.

Smoothing

Controls how the pattern transitions from one part to another:

 

None

Creates sharp, pixelated transitions.

Linear

Creates smoother transitions than None.

Cosine

Creates even smoother transitions.

Cubic

Creates very smooth transitions.  Ideal for use as a height map.

Seed

Changing Seed creates new random patterns.

Iterations

Specifies the number of layers of noise to be placed one on top of the other.  Increasing this value adds increasingly fine details to the noise.
