HDRP Camera Stacking?

Hello Everyone! I am making a game that is situated at an alien planet, so I wanted to make visible in the Sky Some planets and moons that move across the Scene according to the time of the day and the year, following paths defined by a Script. So I though of putting them as spheres in the Scene’s outskirst that are rendered in an camera using the layers and added withing the Main Camera view (Afterall We don’t want to have to render the whole map just to see some planets). But how do I do this camera layering on top of each other (Stacking) in HDRP?

Thanks;
Arthur

Hi,
I think that is supposedly done with the Compositor, but I’ve not had time to try it myself yet.
