How can i pixelate the edges of a model?

[AwesomeGuyUvU (chromakopia)]

1. What do you want to achieve?
   A script that pixelates the edges of a single model, not the whole screen, just like that:
   

   

2. What is the issue?
   I don’t really know how to approach that

3. What solutions have you tried so far?
   I’ve looked through many forum posts, but they all talk about full screen pixelation instead of model pixelation.

I’d also like to know if it would be too laggy, as i’ve seen some people say that screen pixelation is not optimized.
If it’s not possible to only pixelate the edges, then it can be the entire model.
Thank you

There’s no built-in pixelation shader, you could potentially use raycasts to render a pixelated overlay, but that’s a complicated and rather expensive process.
