Render Opacity does not affect outlines

Hello,
I’m trying to make a fade in/out animation for a button, using the Render Opacity property. But the button outline is not affected by the parameter at all.

Bump. Any alternative ?

Which UE version? Is this the same as what I reported here?

[UE5.1] Widget render opacity broken when using border with rounded corners.

It is. However, using Brush Transparency just makes the outline opacity always 0.

I think the only proper way to make buttons with borders pixel perfect and handle opacity properly is to use an image background for each button. I know, I hate it too. Materials are UV space so if you want to specify a 2px border through the shader you are out of luck, or I don’t know a way to get them pixel perfect. Last option… perhaps is research how well SVG is supported these days through plugins and if you can inject color and pixel thickness onto svg data… The options are a bit limited.

*Edit please move this to the bug report section so I can vote on it. It might be seen.

How can I move it to the bug section ?

If you hit the edit button next to the topic title you can change the Category to “Bug report” after which a vote button will appear. You can best unmark the topic as solved if possible so that it still appears to be an open bug which it is.
