10 HDRI 12K Nebula Panoramic Skyboxes

10 high resolution nebula panoramas at 12K, for sci-fi skies, close-up cinematic shots and image-based lighting. Each one is a full 360 degree equirectangular image at 12288 x 6144 in 32-bit HDR, with room to crop and zoom.

Each sky has its own look: pale star clouds on black, warm dusty brown, pink star clusters, silver smoke-like gas, blue and red nebulae, a glowing orange and gold field, a yellow and magenta storm, a bright core on deep black, teal filaments and a soft purple haze.

Good for:
- Sky domes and backgrounds in high-end renders
- Space and sci-fi games, as skyboxes
- Cinematics, VFX and virtual production
- Lighting and reflections on ships and planets

What's in the download:
- 10 unique panoramas in 32-bit Radiance .HDR format, 12288 x 6144 (2:1)
- A contact sheet with numbers that match the file names
- A short README with setup notes for Blender, Unreal Engine and Unity

Every file was checked for bad pixels and the left and right edges join cleanly. Peak brightness runs from about 400 to 19,000, depending on the file, so start with a low intensity. Files of this size use a lot of memory, so limit the size on import if a real-time project doesn't need the full resolution.
