Discovered something even better.
select “SceneCaptureComponent2D” camera in your blueprint (it doesn’t matter if you plan to have more than one copy), In Details, set “Primitive render module” and set it to “Render Scene Primitives”, select “Capture Source” and set it to “(LDR) in RGB”. and create and assign a “render target” to Texture Target.
in your blueprint use “Set Visible” to turn the camera on an off only when you are using it that way you can have multiple cameras.
last but not least set the widget image texture to be the render target texture we created for the camera.
