Hi everyone !

The retainer box widget has some issues when it contains a background blur widget. In the UMG editor, it seems to be rendered correctly, as you can see here :

But in game, nothing is rendered :

Here is the effect material I’m using :

It doesn’t seem to occur with other widgets in UMG, and modifying the effect material doesn’t affect the result. Is there any fix or any workaround, even if it implies implementing it with Slate ?

Thanks in advance.

BackgroundBlur’s workflow is conflicted with RetainerBox, so they can not be used together.

If you only want to apply a mask to control the blur region, see this plugin: Unreal BackgroundBlur With Mask - YouTube
