A LIVING SUN FOR URP AND HDRP
WebGPU Live demo
Amazing and Fast Sun is an animated star for Unity 6. The surface, the halo and the prominences are hand-written HLSL shaders, so you don't need Shader Graph or VFX Graph. Drag a prefab into your scene and you get boiling granulation, sunspots that come and go, a soft glow ring and flipbook prominences rising over the edge.
CLOSE-UP QUALITY
The surface is 3D noise calculated in the object's own space. It uses no UVs, so there are no seams and no stretching at the poles, even with the camera right next to the sun. Granulation flows with domain warping. Up to 20 sunspots grow, shrink and drift around the star, each with a dark core and a lighter penumbra. A Fresnel rim and a separate halo shader finish the silhouette. All colors are HDR and are made to work with Bloom.
PROMINENCES WITHOUT GAMEOBJECTS
The Sun Prominence Generator draws prominences with GPU instancing: one draw call per group, nothing added to the hierarchy. Every prominence lives for a random time and then reappears elsewhere, always on the side of the sun the camera is looking at. Mix several groups with different flipbooks on one sun, and let each prominence pick a random color from an HDR gradient. The generator also runs in Edit mode, so you see the result in the Scene view while you tweak it.
BUILT TO STAY FAST
- Distance LOD: far suns draw half the sunspots, and farther still switch to single-octave granulation with no spots.
- Sunspots can be switched off entirely, which removes their code from the shader.
- One draw call per prominence group.
- Flipbook atlases can be scaled down per platform with the texture Max Size setting.
WHAT'S IN THE BOX
- Sun Yellow, Sun Red and Sun Blue prefabs, for URP and for HDRP
- Sun, Halo and Prominence shaders for each pipeline
- 6 prominence flipbook atlases, from 61-frame strips to a 512-frame 16,384 × 4,096 sheet
- Nebula skybox cubemap
- Demo scenes for URP and HDRP with an orbit / free-flight camera (mouse, keyboard and touch)
- Custom material inspector and full documentation in the Welcome window
GREAT FOR
- Space exploration and strategy games
- Sci-fi menus, cutscenes and trailers
- Astronomy and educational apps
- Mobile space games (URP)
