Circular progress bar

Hi, I want to create a circular energy bar.But only progress bar in UMG. I saw a lot of video on YouTube is achieved with the material. But not perfect. How can I get the circular progress bar?

I think it is more than the time to UE4 leave an update with the circle progressbar in the widgets.
I have also followed toturials and they do not give in the last version

In short, you are correct that it can be done through a material, using a gradient, and comparing that gradient to a scalar parameter with an ‘if’ node. You’d then set the progress of the bar using that parameter.

below is a link to a tutorial showing the process.
