Golden sunsets, blue hour, fog and neon nights - 10 city skylines that light your scene.

10 seamless 8K panoramas of modern waterfront cities from dusk to night: sunset silhouettes, sun rays over a harbour, a violet blue hour, a teal fog, a neon river, a rooftop under storm clouds and a river canyon between towers. Stored as true HDR, so lamps, signs and lit windows keep their brightness in reflections and lighting instead of looking flat.

Unity: drag a material into the Lighting window and you are done - in the Built-in Render Pipeline, URP and HDRP.

✦ WHAT'S INSIDE

• 10 HDR cubemaps - 8192 × 4096 .hdr, imported as cubemaps with 2048 px faces (the full 8K detail), BC6H HDR compression
• 10 EXR + 10 PNG - the same panoramas as 16-bit half float EXR and 8K PNG, for your own tools and for mobile / WebGL
• 10 skybox materials - Skybox/Cubemap, ready to use, rotation and exposure on the material
• Demo scene - switch skies with 1-0 or the arrow keys, look around with the mouse, mirror / glossy / matte spheres
• HDRP support package - 10 Volume Profiles (HDRI Sky) + an HDRP demo scene
• Documentation - README and an illustrated PDF guide

✦ TRUE HDR, NOT A STRETCHED PNG

• Light sources - lamps, signs and lit windows store values up to 24 (a normal image stops at 1.0)
• Everything else - exactly the values of the preview, so at exposure 1 the sky looks like the screenshots
• Lower the exposure - the sky goes dark and the lights stay bright, like a real photo of the scene
• Real reflections - bright highlights on glass, cars, water and metal

✦ WHAT YOU SEE IS WHAT YOU GET

• Every screenshot is an in-engine capture - from the included demo scene, at 1920 × 1080 and a 70° field of view
• 100% crop - of the 8K file in the gallery - judge the detail yourself before you buy
• Seamless - left / right edge checked on every panorama, clean sky straight up and clean ground straight down

✦ DEMO CONTROLS

• Mouse / W A S D - look around · Scroll zoom · Esc releases the cursor
• 1-0 / Left / Right - change the sky · H spheres · Tab text
• Both input systems - works with the old Input Manager and with the Input System package

✦ RENDER PIPELINES

• Built-in and URP - skybox materials + demo scene (the demo spheres use a small shader that works in both)
• HDRP - import HDRP/CitySkylinesDuskToNight_HDRP.unitypackage: Volume Profiles with HDRI Sky, fixed exposure that matches the previews, light bloom

✦ USE CASES

• Games - racing and driving, open-world cities, rooftop and balcony scenes, menus
• Visualization - architecture, interiors with a city view, product shots with real reflections
• Film and VR - cinematics, virtual production backgrounds, 360° VR

Good to know: the extra light range is rebuilt from the image (the light sources), not captured with bracketed exposures - great for highlights and reflections, not a measured light probe of a real place. Looking straight down, some panoramas are softer than at the horizon. Like any 8K panorama, a very narrow zoom on a 4K screen shows more pixels than the image has - 60-90° field of view looks best.
