Using a Render Target as an image directly?

Yes that node Editor Only will only work in the editor and not in shipped version.
You can also export it as .png if that you are trying to do.

Another solution to use render target directly is using it texture rt:

1. Create RT Texture
   

   
   
   
   

2. From your widget, set your image brush to your rt texture(or inside a material)
   

   

3. From your camera / char bp, using SceneCaptureComponent2D setting
   

   

4. Call an event capture when you switch map to capture the scene.
