Another quick way to de-grunge default Poser/DAZ renders. This could be for when you just want a quick-and-meh kind-of watercolour look, and you don’t care that the look is a bit too ‘Photoshop filtered’ and thus unconvincing.
Of course, on top of this you’d then lay in Poser’s comic-books inks or pencil lines from Poser’s Sketch, and lightly blend in shadows.
