7 HDRI 16K Cosmic Luminance Skyboxes

Seven 16K skies with real variety in brightness, from a nearly black star field to a bright, pale sky that fills a scene with soft light. Pick the one that sets the exposure you want.

The bright end has a silver-grey sky with dark round voids, a pale olive sky with a small glowing ring, and a rich gold sky fading into dark teal. The darker end has a lilac star cluster, sweeping grey and violet clouds, a white cloud on black, and a warm white and rust nebula.

Best for:
- Lighting tests and look development in space scenes
- Bright sci-fi skies that aren't the usual dark space
- Cinematic backgrounds at close range
- VR and dome projects

The download has:
- 7 panoramas in 32-bit Radiance .HDR, 16384 x 8192 (2:1 equirectangular)
- Numbered contact sheet
- README with notes for Blender, Unreal Engine and Unity

Each cosmic HDRI gives you a sky and image-based light in one file, and the HDR image keeps bright detail for reflections on your space scene.

Every file was checked for bad pixels, and the left and right edges join cleanly. Good to know: peak brightness runs from about 63 to 13,000, because a few small points are very hot. Lower the intensity or clamp the highlights if you see fireflies. Large files use a lot of memory, so limit the size on import where the full resolution isn't needed.
