Substance Painter: Flow Map-driven Generator options?

Does anyone know of an existing plugin/generator that will take a custom flow map, and use that flow map to generate and guide procedural markings/strokes so that they follow a direction in general?

And would that above description need more explanation?

For example, let’s say I want to procedurally create noise-brush strokes that follow a custom made hair asset mesh “shell.” And I can custom paint the flow map in Substance Painter. So when I use that generator in a mask or a bitmap, I can input in that custom painted flow map, and it will generally create lines/patterns/strokes based off the direction of the flow map.

Hi! I’m currently looking into the same thing, did you manage to find something?
