12 HDRI 8K Sci-Fi Galaxy Skyboxes

Twelve galaxy-style skies with plenty of stars and colour, made for sci-fi worlds. Most have depth from large foreground stars in front of soft clouds.

The mix includes a teal and pink star field, an ocean-blue sky with a pale central cloud, purple and cream around a bright core, and warm orange star clusters on brown-black. Quieter options include white gas with sparse stars. There's also a gold and yellow nebula, a crimson sky with white wisps, and a pale sand and lilac sky with thin arcs of light.

Made for:
- Space exploration and strategy games
- Planet surface skies seen from an alien world
- Sci-fi film, animation and concept art
- VR and 360 degree environments

What's inside:
- 12 panoramas, Radiance .HDR, 8192 x 4096 (2:1 equirectangular)
- Numbered contact sheet
- README for Blender, Unreal Engine and Unity

Each galaxy HDRI can serve as a sky dome or an environment light, and the HDR image keeps star highlights for sci-fi reflections.

Each file was checked for bad pixels, and the left and right edges join cleanly. Peak brightness is about 24 to 2,350, because some stars are very bright, so lower the intensity if highlights look too strong.
