Three detailed starry skyboxes I put together using real life NASA images.

The base is this NASA star map HDRI (https://svs.gsfc.nasa.gov/4851) that I colour graded then converted to a 2048x cube map. Since there’s no proper orientation when it comes to space, this skybox can be rotated in any direction, to place the milky way exactly where you want it to appear in your map. (Used in my Galileo 2 Starliner map: https://www.factionfiles.com/ff.php?action=file&id=8119 )

For the Jupiter variant, I took a spherical texture map of Jupiter, colour graded it, then applied it to a sphere in Bryce, then lit it and rendered it out at 3072x resolution from there. Then I just applied it to a face brush in the skybox. Then the 4 Galilean moons are NASA images that I just cropped/alpha masked and applied to other faces in the skybox. Since the 4 moons and Jupiter are separate brushes, this allows you to resize them and move them around the sky as desired, or completely remove the moons if you don't want them.

For the Mars variant, I found a high resolution NASA image of Mars, colour graded it, synthesized some of the missing edges to make it a full sphere, alpha masked it, then applied it to a face brush in the skybox. Since it's on a separate brush, this allows you to resize and move it around the sky as desired. (Used in my Boingy 3 map: https://www.factionfiles.com/ff.php?action=file&id=8193 )

They all have a RF group file that you can just import into your map and be good to go. I've also included DDS versions of the textures, which you should swap with the TGA's in the VPP, when you're ready to release, for much smaller file size.
