Vertical Noise

Vertical Noise Modifier. This modifier is basically a noise modifier but instead of acting on all 3 axis of a mesh it acts in the vertical direction so is useful for doing a terrain where only vertical noise is needed for example. If you don’t want noise on the Y axis you use the Gizmo Rot values to orientate the noise in any axis you want not just the major axis so you have complete control. The fact the noise only happens on a single axis makes it faster than the noise modifier. This noise modifier also has a decay feature to allow you to reduce the effect over distance.

Vertical Noise Param Description


Sets the size of the noise effect (not strength). Larger values produce smoother noise, lower values more jagged noise.


Sets the periodicity of the sine wave. Regulates the speed of the noise effect. Higher frequencies make the noise quiver faster. Lower frequencies produce a smoother and more gentle noise.


Shifts the start and end points of the underlying wave.


Allows the effect to fall off with distance.


Set the strength of the noise effect.


Regulates the combined effect of Noise and Strength parameters. The following parameters adjust the underlying wave.


Produces a fractal effect based on current settings. If on extra settings will appear.


Controls the number of iterations (or octaves) used by the fractal function. Fewer iterations use less fractal energy and generate a smoother effect. An iteration of 1.0 is the same as turning Fractal off.


Determines the extent of fractal variation. Lower values are less rough than higher values.
