16K Galactic Nebula Skyboxes – 5 Seamless Space HDRI Panoramas

Full 4K video walkthrough: https://youtu.be/AHBVjzhqeZ4

AAA Galactic 16K Panoramas - five seamless 16K (16384 x 8192) space HDRI skyboxes for Unity. Deep crimson and silver cores, golden storm filaments, rose veils, frosty ember clouds and a dark dust cradle: every panorama is a full 360 degree nebula environment with a natural high dynamic range and deep blacks.

WHAT'S INSIDE

- 5 x 16K HDR skyboxes (Radiance .hdr imported as Cubemap textures)

- 5 Skybox/Cubemap materials, exposure tuned per sky

- 5 example scenes - press Play and look around with the mouse, WASD or arrow keys; scroll to zoom

- 3 x 16K 32-bit float OpenEXR masters (CrimsonCore, GoldenStorm, AzureDustCradle)

- Seamless at the 360 degree wrap and clean at both poles

About the EXR masters: the Asset Store limits a package to 6 GB, so there is room for 3 of the 5 EXR masters. The HDR files hold all 5 skies at full 16K resolution with a full high dynamic range.

HOW TO USE

Open any scene in Example Levels and press Play, or assign a material under Window > Rendering > Lighting > Environment > Skybox Material. Ambient light and reflections can use the skybox as their source.

USE CASES

Space games, sci-fi cinematics, image-based lighting, menu and title screens, trailers, VR space scenes.

Every screenshot and the video show the raw HDRI at a fixed exposure per scene - no post, no colour grading. What you see is what you get.
