This nodes generates a classic Perlin Noise shape, with softer random blobs at a user-selectable scale. It is useful because it is simple and cheap, yet it provides a slightly harsher and more artificial look than Gaussian Noise (mostly due to simple Box-blur interpolation vs Gaussian interpolation).
If you're used to the older, classic Perlin Noise nodes (such as Perlin Noise Zoom) from before Designer Version 2017 2.1, Gaussian Noise comes slightly closer to those. However, this new Perlin Noise is more correct in the technical sense.
- Scale: 1 - 256
Sets the global scale for the effect.
- Disorder: 0.0 - 1.0
Phase-shifts the noise to introduce small variation.
- Non Square Expansion: False/True
Enables compensation of squash and stretch with non-square ratios.
