Widget Component not rendering into SceneCapture2D

Hello everyone. I’m using a setup like the one below in order to render a Widget rotated in world into a RenderTarget Texture.

The only problem is that the texture rendered doesn’t has the Widget component into it, as it’s invisible.
Someone could achieve the effect I want? Because I already tried so many things that I think it might be an engine issue.

As a matter of fact the Widget component only renders in the editor. When I run it, it disappears.
