Free Sketch Filter Substance Designer

This is a sketch filter node I made in substance designer. 

It takes in a height map / Ao map (depending on how you want it to be generated) and creates a pen sketch version of it. It is pretty basic so it is limited in its ability but I hope someone can find it useful. 

I was sitting on it for a while and though it would be good to finish it up and share.

Enjoy
