Hi everyone! Do you remember the video about detecting edges using the Sobel operator, which we enhanced by using Gaussian blur? One of the drawbacks of Gaussian blur is that it’s somewhat computationally intensive, which can pose some performance issues for our game if we want to apply such an effect in real-time. In this video, I will demonstrate a much faster way to blur our sprite or the entire screen.
Well, Godot is a lightweight engine, so it doesn’t have almost anything extra built-in. Which is advantageous because the engine itself then takes up negligible space on disk and the editor starts up within seconds, which can’t be said for Unreal. But everyone prefers something different, of course. I mainly wanted to show that implementing your own blur effect can be simpler than it might seem at first glance.
