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.
