Hi, in one of my games I would like to be able to toggle "old school" mode which would simulate large pixels. So I would like to, essentially, pixelate the entire screen/stage with pixels of specific size.
I thought a shader might be a good way to go about this so I tried messing with the blur samples, but alas, shaders are still a bit over my head.
Simple example of what I mean:https://www.photofunny.net/efectos/grandes/pixelate_images.jpg
Any ideas on how to best accomplish this?
