Good day everyone. For the last few days i've been trying to make a pixelation image effect for unity pro, with a pixel shader, but without success. I want to make a defined rectangular area of the screen to go pixelated. The exact effect is like the one shows in the sims games, when the game needs to censor them. Like this. I've been trying a lot of things and searched over the web for hlsl tutorials, reference and whatever, but i cannot make it. The only i got to work is making the effect by converting RenderTexture to Texture2D and using SetPixels() in the selected area, but it is obviously very slow. I need a pixel shader for this. Any help is very appreciated. A link to a tutorial, a piece of code, slight advice, whatever is useful. Thanks in advance.
