Gaussian Blur is an Unity shader available on the Asset Store. As you might have guessed from the name of the asset, Gaussian Blur is a Blur shader! 🙂
I keep looking for a blur shader that looks decent. It’s a bit strange that I wasn’t able to find to many assets like this. Anyway, Gaussian Blur is a shader developed by Flying Banana. It comes with two versions, Normal & HQ.
You can apply this shader to any material. That means: a 3D object, an UI element and even an world space UI element. Think of The Division world space’s UI and how they use the blur for the background of the UI elements.
Those are the settings that the shader currently has. Everything is pretty straight forward, however I also recommend to watch my video from below 🙂
