Change direction the 3d widget faces?

The 3d widget has a geometry mode, with Plane or cylinder. But when I choose cylinder, it’ll only draw on the inside of the cylinder. How do I get it to draw on the outside of the cylinder? changing the arc angle to a negative just defaults to 1.

Ok here’s an example I threw together.

The back is solid black, but I would like the actual widget facing outwards. And if possible, I’d like to have transparencies and such for a floating menu.

I’ve got a render canvas to target working, and then the target applied to a material, sortof following this tutorial: Creating Textures Using Blueprints and Render Targets | Unreal Engine Documentation
And with that I can draw boxes and text and such, and change them however with blueprint.

But it would be a lot nicer/easier if I could render a widget to the rendertarget. Any ideas?

Have a look at UMG Retainer Box - renders widgets to Render Target.
