### Remarks

When this is set to `true`, this Scene uses the Enlighten Realtime Global Illumination system. When this is set to `false`, this Scene does not use the Enlighten Realtime Global Illumination system.

When Unity serializes this `LightingSettings` object as a [Lighting Settings Asset](/engine/6000.5/manual/lighting-overview/lighting-reference/class-lighting-settings.md), this property corresponds to the **Realtime GI** property in the Lighting Settings Asset Inspector.
