How do I make Background Blur's Corner Radius change with the size of the viewport?

[Chikako_Tani]

Hello.
Please forgive me for asking this question in my poor English.

I have just started the game with the Corner Radius of Background Blur in WBP set to a value,
The Corner Radius does not change with the size of the viewport, resulting in an unintended shape.
The DPI Scale is set and the size of the UI image changes with the size of the viewport.

Please let me know how I should resolve this issue.

Hey, your method seems good, but one question - for your corner radius, did you just put the amount in pixels or something else? Because I’m still getting unintended shape, which also changes when ran in Standalone for some reason.
