This chalk drawing filter allows you to input any grayscale image (black and white line drawings or text work best) and output an adjustable, chalky result. Parameters have been exposed for various effects, such as dust coverage, distance and scale of the smudgy haze as well as aging the final result.
Throw the .sbs into your Substance Designer root folder to bring it in with the space bar menu and create some decals and effects. Or just open the graph and check out how I made the effect work with the included demo.
There was an error with a custom node unable to find its reference. Node has been removed and I've also added the .sbsar file.
