How to light a space scene,cant bake lights, procedural level creation

Our game is unique, its procedurally spawned when the level starts. I am creating a space scene, and my issue is trying to get good reflections on space junk,space statons, and anything metal at all isn’t really working out . Anyone got some lighting tips or anything that could help out when it comes to lighting a space scene. Currently I just have a directional light, and I had to dial its roughness down so the specular wouldn’t be so massive. Still though I cant really use reflection captures if I understand it correctly because we cant bake lighting and our objects are always moving. Also ambient cube map wont work because it puts ambient light on the dark side of objects. I know I could fake it with a ambient cube map and wiring in a dot product to every object material, but that sounds tiresome, and expensive to me.
Here is a link to a video showing currently what lighting looks like.
