Space HDRI skies

What is in this collection

8 published HDRIs sit in the Space category. Prices range from $9.90 to $25 per variant. Formats include a standard equirectangular panorama up to 20000px wide, and a 6-tile cubemap version at 2048px or 4096px per face for engines that prefer cubemaps over a single spherical image. Examples: HDR 180-1 Space Sky and Stars, HDR 180-6 Space Sky with Planet and HDR 180-8 Space Sky with Nebula.

When to use space HDRIs

• Spacecraft, satellite or space station renders needing a starfield background with no ambient sky light.
• Sci-fi product presentations that put an object against deep space instead of a studio backdrop.
• Game or real-time engine skyboxes, using the cubemap variant to avoid the seam and pole distortion of an equirectangular map.
• Compositing work where the sun, planet or nebula variants let a single base scene be dressed differently per shot.

Rendering notes

Space HDRIs mainly supply background and faint fill light rather than a strong key light, since there is no sun disc bright enough to define hard shadows unless the sun variant is used; add a separate directional light for the main illumination on any spacecraft or object in frame. The cubemap format renders each of the 6 faces independently, so it maps directly onto a game engine's skybox without the reprojection an equirectangular file needs.
