How do I render a particle system as if its fixed to a camera?

Hi, I have a starfield which I want to implement via a particle system for various reasons.
I would like it to always render behind other objects and always be the same distance from the camera.

If I was using unity I think I would just have two cameras one which is stationary but rotates to get the starfield only and another normal camera to move through the rest of the map geo and just combine them. In unreal I’m not sure what my workflow should be, ideally I would avoid engine changes. Any advise would be greatly appreciated.
