Volumetric Nebula Skyboxes 2 – 17 Fly-Through 3D Space Nebulae (URP & HDRP)

Fly into real 3D space nebulae – and give them any colour you want. 17 truly volumetric nebulae for Unity, rendered in 3D all around the camera: fly into, through and around glowing gas and dark dust. This is not a skybox image. A new, more realistic style: bright star-forming cores, dark dust pillars with lit rims, thin veils, thick dust lanes and dark voids with stars between them, in natural, muted astrophoto colours – and every colour is customisable, live.

URP and HDRP in one package: 17 URP + 17 HDRP demo scenes, one Nebula Volume component, works in the Scene view while you edit.

WHAT'S INSIDE
- 17 volumetric nebulae – each with its own shape and palette: a profile, five 3D textures and an 8K star and galaxy layer
- 34 demo scenes – 17 for URP, 17 for HDRP, each with a fly camera at a chosen start view
- Nebula Volume component – profile, quality, size, copies, gas animation and colours, live in the editor and at runtime
- Nebula Fly Camera – the demo controls, ready to put on your own camera
- URP renderer feature (one-click setup) and HDRP custom pass (already in the demo scenes, one menu click for your own scenes)
- Documentation – README with quick start, every setting, colours and performance tips; commented C# and shaders

Cinder Red · Steel Rust · Rose Teal · Olive Smoke · Ash Violet · Hydrogen Red · Violet HII · Oxygen Green · Crimson Rose · Emerald Gold · Purple Gold · Magenta Dust · Azure Reflection · Crimson Pure · Violet Blue · Emerald Teal · Magenta Blue

NEW: EVERY COLOUR IS CUSTOMISABLE
- Gas palette – Gas Outer, Gas Mid and Gas Core (HDR colours), from the faint outer gas to the bright cores
- Dust – Rim Color for the lit rims of pillars and dust lanes, Dust Glow inside the dust
- Grading – Saturation, Hue Shift, Emission Gain, Density Scale
- Sky – Star Cut, Star Gain, Sky Exposure and Sky Tint of the star layer
- For every scene or just one – edit a profile's Look, or tick Override Look on one Nebula Volume; "Reset Look To Design" brings the original back
- Live and from code – changes show instantly in the Scene and Game view, and every value can be set from C#. Light and shapes are baked colour-neutral, so any palette keeps the full 3D look

FEATURES
- Fly inside – the nebula surrounds the camera 360°, with gas and dust at every depth
- Four quality presets – Low, Medium (default), High, Epic
- Scale x0.25 – x16 – the whole nebula grows, with the same look and the same cost at every size
- Rotated copies – repeat a nebula around itself into one huge, seamless nebula while the close-up detail stays sharp
- Slow, natural gas animation – on by default, off for a perfectly still nebula
- Own deep-field star layer – or untick Draw Stars and use your own sky; the nebula is composited over whatever is behind it, and objects inside it are fogged naturally
- Self-lit – no lights needed
- Works next to Volumetric Nebula Skyboxes (pack 1) in the same project – own folder, namespace and menus

PERFORMANCE
Four quality presets scale performance; cost depends on screen resolution and preset, not on nebula size or colours.

USE CASES
Space games and flight sims · sci-fi cinematics and trailers · menu and title backgrounds · space-station and planet backdrops

Note: very close to dense dust the clouds become soft (the volume's resolution). The nebula is drawn before transparent objects.
