# OvrLight

### Description

This Node is used to manage the most common interactions with the Unity [Light](https://docs.unity3d.com/ScriptReference/Light.html) Component.

This OVER Component requires a Light to be set up. See the [Unity Manual](https://docs.unity3d.com/Manual/LightingOverview.html) for more info.

Based on the action the Light is required to perform, this component changes its behavior and requirements.

### Action Types

The OVER SDK provides several ways to interact with Unity Light Component. A list can be found in [OvrLightActionType](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/unity-components-interactors/ovrlight/ovrlightactiontype.md).
