Mask Background Blur Widget

Hello!
I have tried all the ways I could think of to mask a “Background Blur Widget” to get the result you see in the image:

But I have been unable, I think the problem is that I don’t know how to use the image section:

(The image is taken from the official unreal 5 guide.)

Or maybe it has something to do with the “alpha” section that I don’t quite know where it comes from either (since I don’t know which alpha it refers to).

Greetings and thanks in advance.

Blur strength - you can see it working immediately :slight_smile:

Thanks, but that’s not the problem. Maybe I’ve explained myself wrong, but I want to make a mask, I don’t want a blurred square, I want the blur to have a certain shape.

The best example is this one (although I want to do it with the tools that unreal already has and not pay to do it):

Ah… The only example of success I saw, was someone who modified the engine… :-/
