Smooth Stepping Curve Function

Remap Noises for Stylised Looks

This is the first time I dive into the Pixel Processor node in Substance Designer, shut out to AndrewA1988 and the “Tone Curve Set” filter he uploaded on Substance Share, which helped me understand more functions in SD:

With this function, I could quickly remap the values of procedural noises, to give them a stylized treatment.
This tool was heavily used in the making of the previous project I posted: Bond – Blue Period Painting


The idea came from using a Curve node.
I wanted a node with full control of the stepping curve so that I could iterate faster.

Control on the smoothness of the steps
Control on the number of steps

The remapping it’s applied to the noise using a “Gradient (Dynamic)” node
Treatment applied on different noises, it also works on grunges and a Blur node helps to soften the edges.

I cannot take credit for the function, it was posted in this forum https://tinyurl.com/3wkard7n
and here is WolframAlpha’s link https://tinyurl.com/2p83ndvs
