10 HDRI 12K Plasma Energy Skyboxes

10 plasma and energy panoramas at 12K, for sci-fi skies, abstract backgrounds and space scenes. Each one is a full 360 degree equirectangular image at 12288 x 6144 in 32-bit HDR.

Most of the set is warm: glowing orange and gold plasma filaments on dark backgrounds, golden star clusters, and a copper sky full of curved energy lines. One panorama is a violet and pink nebula. Three are soft, bright hazes in amber, gold and pale rose with very little fine detail, for scenes that need a filled, glowing sky. Those three share similar shapes in different colours.

Good for:
- Sci-fi game skies and alien worlds
- Energy, reactor and portal environments
- Abstract backdrops for product and motion renders
- VR and 360 degree backgrounds

What's in the download:
- 10 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 14 to 221, depending on the file. 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.
