A post effect for a halftone look, made in Unreal. The concept is borrowed from the chapter "Mobile Toon Shading" in GPU Zen 01, developed Felipe Lira, Flavio Villalva, Jesus Sosa, Kleverson Paix~ao and Teofilo Dutra, where it's used in a shading model.
Originally, my goal was a printed look with cmyk dots, but turns out it needs an absurd amount of dots before the colors blend together. The monochromatic look is easier to read for the viewer.
