20 HDRI 8K Earth Stratosphere Skyboxes

20 panoramas of the view from Earth's upper atmosphere, with the curved horizon, cloud layers below and space above. Each one is a full 360 degree equirectangular image at 8192 x 4096, ready to use as a sky dome or backdrop.

The set moves through different light: bright sun flares on the horizon, blue daylight over scattered clouds, fiery orange and pink sunsets, a night side with city lights, and dark skies with a band of stars arching overhead.

Good for:
- High altitude flight and spacecraft scenes
- Orbital backdrops in sci-fi games and films
- Backgrounds for vehicle and character renders
- VR and 360 degree backgrounds

What's in the download:
- 20 unique panoramas in Radiance .HDR format, 8192 x 4096 (2:1)
- A contact sheet with numbers that match the file names
- A short README with setup notes for Blender, Unreal Engine and Unity

Good to know: peak brightness in these files is about 1.0, so they look their best as visible backgrounds. For strong sun shadows, add your own directional light.
