Anisotropic noise

This generates a stretched noise. It is one of the Noises with a higher number of parameters, making it a little trickier to use. Keep in mind that the stretch effect is mostly determined by the proportions between the X and Y amount.

A very useful node for creating grain-type patterns (like wood grain).

Parameters

• Amount - Amount of X and Y repetitions of the pattern. By default this is set very low compared to the Y, leading to the stretch. Reduce it even further to get less X-axis variation
• Rotate - Rotates the entire effect 90 degrees. X becomes Y and vice versa.
• Disorder - Phase-shifts the noise to introduce small variation.
