Performance Controls
| Setting | Higher Value Does | Lower Value Does |
|---|---|---|
| Visual Update Frequency | Updates visuals less often for better performance. | Smoother transitions. |
| Min Time Change Threshold | Skips very small visual changes. | Updates more subtle time changes. |
| Sky Light Recapture Interval | Recaptures skylight less frequently. | More responsive ambient lighting changes. |
| Aggressive Optimization | Reduces material parameter updates further. | Keeps the most responsive visual updates. |
| Sky Light Cubemap Resolution | Sharper captured lighting, more cost. | Lower cost, softer captured lighting. |
Common Fixes
| Issue | What To Check |
|---|---|
| Sky does not move during Play | Enable Time Of Day Cycle and raise Time Speed above 0. |
| Stars visible during day | Lower Star Brightness Min, check SkyOpacity behavior on your custom material, and use the actor-driven parameters listed in this guide. |
| Clouds too strong at night | Lower Cloud Opacity Night, Cloud Opacity Max, or the material's CloudOpacity value. |
| Clouds look blocky or pixelated | Raise Panning Cloud Quality and lower Panning Cloud Global Tiling on the SkyBox Time of Day Actor. |
| Moon is not visible | Enable Moon, check Time Of Day, make sure the moon is above the horizon, and verify Moon Scale and Moon Brightness are not too low. |
| Moon path looks clipped or jittery | Raise Max Visual Elevation in Moon Parameters. Low values can flatten the moon arc near transit. |
| Moon craters overlap or look stretched | Use the actor's Moon Parameters crater controls. The default shader uses evenly distributed view-disc craters to avoid random cluster overlap; lower crater count or radius if you want a cleaner moon. |
| Moon glow is not visible | Raise the moon material Brightness and enable post process Bloom. Bloom should glow from the moon surface, not from a separate circular halo mesh. |
| Scene is too dark at night | Raise Moon Intensity, Sky Light Intensity, Auto Exposure Min Brightness, or Ambient Fill on the moon material. |
| Sun glow looks too harsh | Lower Lens Flare settings or prefer Bloom for a smoother glow. |
| Sky light feels delayed | Lower Sky Light Recapture Interval or call Recapture Sky Light after a large time jump. |
