The Pattern Shaper Node recalculates an Input using Partial derivatives. The results are shaped patterns.
Below we can see the effect of the Pattern Shaper Node on a simple Perlin Noise.
The Node always requires some sort of gradient between values to work.
Procedural Inputs vs Result of Image Operations
If the operation is run on the result of an image operation (e.g. paint, bake points etc.) you might encounter artifacting as
each pixel compared to its neighbor will have a change in value. This is a limitation of the algorithm.
Node Overview
Node Ports
•Output
Returns the transformed Noise or Pattern
•Noise / Pattern
The Noise or Pattern to transform. The Input should contain gradients, as hard contrasted patterns will not give any results
Node Properties
•Contrast
Modifies the Contrast of the shaped Output
•Contrast Pivot
Defines the value that is used as a midpoint for the contrasting operation. Values below the pivot will get darkened by the contrast, values above brightened.
•Contrast Multiplier
A multiplier against the "Contrast" Slider
•Horizontal Shape
Allows you to limit the calculation to horizontal shapes only
•Vertical Shape
Allows you to limit the calculation to vertical shapes only
