How to create a viewport in a widget

I am basically trying have the picture-in-picture feature that is used with Cine Cameras in the viewport and apply that to an editor widget I am creating. I have been looking at the source code for the picture-in-picture feature and it seems like I have to create a viewport inside a widget. Is there an inherent way to do this? I have been working with the source code and blueprints so any insight on either fronts would be really helpful!

Would a render target be enough?

I have used render targets in the past and to my knowledge they don’t show some of the cine camera elements that need to be shown in what I’m trying to do. I need the full preview of a cine camera (including focal length and aperture) in the widget. Do render targets allow for these features?

Technically speaking, it’s the Scene Capture Component that does the heavy lifting here:

It’s quite limited, though. Render Target writes it to a texture.

Not sure how to work in those advanced features of Cine Cam, found this:

Seems to be a dead end, sorry.

Not exactly what I was looking for but what was mentioned on the forum is applicable to what I’m doing so thank you for the info!
