UI Blur

I want to make a game that is like a os. imagine it would be mac os and you look at the dock at the bottom. It Blurs the Background right? i made a background it is an image and i made a panel in front of it at the bottom so it looks like the mac os dock but i cant get it blurred because every tutorial is about the blur in a pause menu and the background. So can someone help me?

Hey there, that’s not really an accessibility question, so I can forward your question to maybe one of our UI systems depending on which one you’re using. Do you have a Canvas on your scene, or are you using UI Toolkit?
