Just opening a personal sketchbook thread to throw whatever I feel like to publish…
This is a shameless inspiration by Hi-Fi Rush’s dot effect.
Hi-Fi Rush is very pleasingly stylish that it incorporates the Ben-Day/halftone dot pattern for the comic shading effect. It’s not really transforming the whole screen into CYMK print, that would be too noisy. Rather the dot pattern is employed sparingly where they are actually effective like the comical striking particles and onomatopoeia, but one particularly interesting place which uses the dot pattern is its bloom PP. I made some poor attempt to recreate it but did not have too much success. This is what I ended up with at the moment, only translucency is given the halftone treatment.
The halftone pattern is very simple, just frac the Viewport UV and get the vector length of each grid, then step(grid pattern, PP input). PP input 1 under Before Tonemapping gives you separated translucency so it doesn’t affect the opaque objects. Unfortunately, the PP still gets the ghosting artifact when the pixel is rendered before the opaque object.
