# LightBakingOutput

> Struct describing the result of a Global Illumination bake for a given light.

## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public struct LightBakingOutput
```

## Remarks

The example below demonstrates how you can check the baked status of a light and change its active state.

## Examples

```csharp
using UnityEngine;
using System.Collections;

public class LightBakingOutputExample : MonoBehaviour
{
    void TurnOffLight(Light light)
    {
        if (light.bakingOutput.isBaked && light.bakingOutput.lightmapBakeType != LightmapBakeType.Realtime)
        {
            Debug.Log("Light got some contribution statically baked, it cannot be turned off at runtime.");
        }
        else
        {
            light.enabled = false;
        }
    }
}
```
