Best Workflow
- Choose an included material instance that is close to the look you want.
- Duplicate it into your project folder.
- Rename the duplicate for your level, biome, or sky style.
- Adjust the exposed material parameters.
- Assign the duplicate to Sky Sphere Material on the SkyBox Time of Day Actor.
- Use the actor's cloud opacity, star brightness, and time settings for the day/night transition. Adjust horizon, zenith, and cloud colors on the material instance.
Main Materials
| Material | Best For | Notes |
|---|---|---|
| M_PanningClouds | Readable skies with moving cloud color, sun glow, horizon color, and stars. | Good default choice for time-of-day scenes. |
| M_ProceduralSkySimple | Procedural color bands, noise variation, star field, and curl/Worley variation. | Best when you want direct material-instance tweaking. |
| M_LayeredProceduralSky | Layered material workflows using the included material layers. | Use with layered sky, nebula, Musgrave, Perlin-Worley, Simplex, star field, and northern lights layers. |
| M_Moon | Procedural moon surface and phase rendering. | The actor can drive moon phase from Time Of Day during play, or you can disable Enable Moon Phase and use the material instance MoonPhase value directly. |
Preset Groups
