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).
- X Amount: 1 - 512
Amount of X-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.
- Y Amount: 1 - 512
Amount of Y-repetitions of the pattern. This determines the amount of "stripes".
- Y Amount By Resolution: False/True
Ties the Y-amount to the node resolution. Useful for keeping scale when you want to go bigger; avoids having to manually change the Y-amount.
- Rotate: False/True
Rotates the entire effect 90 degrees. X becomes Y and vice versa.
- Smoothness: 0.0 - 1.0
Controls the additional anisotropic (motion) blur over the X-axis. Recommended not to reduce it unless the X-amount is 1.
- Smoothness Interpolation: 0.0 - 1.0
Additional control for the smoothness, with minor influence on the stretch length.
- Non Square Expansion: False/True
Enables compensation of squash and stretch with non-square ratios.
