Generating procedural star fields based on positi

Hi all, total noob here. I’m currently working on a procedural universe where a player travels to individual star systems (which is a separate level) through a warp transition. But the problem is, I need to able to generate a skybox with all the stars/objects visible from that particular system (based on its position within a galaxy) which I have no idea how to. I can kinda imagine how to get the positions of the stars to place on the cubemap, but other than that I’ve never worked with skyboxes before and have no idea how to proceed. Any help? Thanks!
