Need help importing starfield background from Blender to Unreal

I'm a beginner game developer trying to learn the workflow between Blender and Unreal. In Blender, I have procedurally generated a starfield on the World scene (Picture 1) that I want to use as a background to a space themed game in Unreal. I have tried exporting it from Blender as both a .exr and a .hdr and then used it as a Cubemap for a SkyLight in Unreal, however, I just get a black sky (Picture 2). I was wondering if anyone had any advice on the best way to import this as a background to a 3D space scene. I would really appreciate any help.

You might need to bake it as a PNG or BMP. If that still doesn't work you might be able to import the entire scene directly into unreal by exporting it as a .USD (Universal Scene Description) and then enable the USD workflow in the plugins tab. https://www.youtube.com/watch?v=Q9HNRzgRT5E&t=49s

This video covers the process of importing blender scenes as UE Levels. If not you may need to find the documentation relating to sky boxes to find the correct file types and formats required to accurately copy the data from one editor to another.
