Smooth Stepping Curve Function - Remap Noises for stylized look
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.

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

The graph of the function recreated in Substance Designer using the "Pixel Processor" node
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: https://www.artstation.com/artwork/6bOWRN
