• One of the following Shape components: Axis Aligned Box, Box, Capsule, Compound, Cylinder, Disk, Polygon Prism, Quad, Shape Reference, Sphere, or Tube, to define the Gradient Transform Modifier’s area.

Noise types

Noise Type	Description	Example Gradient
Value	Generates a White Noise gradient based on interpolated values from XYZ-coordinates.
Value Fractal	Results from the Value algorithm are run through a fractal function.
Perlin	Generates values from the Perlin noise algorithm, a noise algorithm where visual features are all of similar size.
Perlin Fractal	Results from the Perlin noise algorithm are run through a fractal function.
Simplex	Generates values from the Simplex noise algorithm, a variation of Perlin noise with fewer directional artifacts.
Simplex Fractal	Results from the Simplex noise algorithm are run through a fractal function.
Cellular	Generates values from a cellular noise algorithm, which assigns values based on randomly distributed feature points; each world position is assigned the value of the closest feature point.
White Noise	Generates values from XYZ-coordinates, which produce extremely different values for adjacent samples.
Cubic	Generates values directly from XYZ-coordinates that are then run through cubic interpolation with neighboring values. The results are similar to Perlin noise, but with fewer directional artifacts and with a higher occurrence of extreme values.
Cubic Fractal	Results from the Cubic noise algorithm are run through a fractal function.

Note:

Not all combinations of Noise Type and noise property settings have the same performance characteristics.
