This is a shader effect designed to produce a classy printed-poster look. There are parameters for scale, contrast, brightness, noisiness, CMYK ink colors, ink offsets, and more!
I've put this asset at $5.00, however, you can download it for free on itch.io (link below) if you cannot afford it here. I don't want pricing to be a barrier to my assets. I hope that you will like it enough to choose to support my work. Thanks!
Inspired by MRMO's Halftone filter, but rewritten from scratch for GameMaker (I never looked at its source code).
