I created a basic pixelation shader, free to use. The 3D model of the subway car was created by Luc Miramont on sketchfab. The shader you can download below is slightly more advanced than in the video. It has 2 scanlines and some more parameters.
Are you nostalgic for the past? Let's see how you can achieve this cool retro effect in a 60 second #shadersdonequick tutorial! 📺 You can get the graph here https://t.co/FkXTd3gS9E #unitytips #madewithunity #indiedev #gamedev #tutorial #shaders pic.twitter.com/MfuKdlQi5g— Alexander Ameye (@alexanderameye) April 6, 2020
The effect uses a custom render pass to apply the effect as an image effect to the scene. I included the renderer and pipeline asset in the project. Basically you go to your renderer and add the 'Pixelate Pass' as a renderer feature. Then you drag the pixelate material into the slot and you're done!
