Perlin Noise by Miguel A Santiago Jr








Perlin Noise is a more advanced version of Mari's default Perlin giving more control options


Samples



Options


Color


The two colors that make up the final look of the procedural

Size


Size of fractal features on your model


A random start value for your fractal.

Changing the seed changes the overall look of your fractal while the general feature look stays the same,

allowing for quick variation with a general look theme.


Modifiers



This Perlin Noise implementation lets you choose from 3 different noise types, each giving slightly different results with the same settings


Perlin, Simplex, Value




Defines the Value at which point the noise will be tipped towards color A (values to the left of the set slider value)

or color B (values to the right of the set slider value).


Clamps the noise calculation to a 0-1 range.

Color A/B are applied after the Clamping, so you can still set values above 1 if you choose to

however by clamping the Noise calculation the color mixing between the two colors works more

reliably. In general this should be left on.


Inverts the result of the noise. Inversion is done before color A and B are applied.


Space


By default this procedural is generated in 3D World Space. This results in a seamless noise across UV seams.

By turning on UV Space the procedural is generated based on your UVs, resulting in seams between UV tiles/UDIM & uv shells.


Utilizing Transform Controls such as Scale (see below) you can apply a non-uniform transform to the procedural

to make use of specific UV layouts

Transform Scale


Will apply a scale along X,Y or Z to your noise. This is useful for creating patterns like woodgrain, drips etc.

When UV Space is turned on Scale Z is ignored.

Transform Rotate


Will apply a rotation in X,Y or Z to your noise. When UV Space is turned on Rotate X & Rotate Y are ignored

and rotation is done around the center of each UV Tile/UDIM using Rotate Z.

Transform Translate


Will apply an offset in X,Y or Z to your noise. When UV Space is turned on Translate Z is ignored.
