# LightProbeGroup

> Specifies where and how to bake a list of light probes.

## Definition

* **Type:** Class
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule
* **Inherits from:** [Behaviour](/engine/6000.7/script-reference/unityengine/behaviour.md)

```csharp
public sealed class LightProbeGroup : Behaviour
```

## Remarks

Light Probe Groups act only as input for Unity’s light baking system and have no direct impact on rendering.

Light Probe Groups do not affect probes used by other systems such as Reflection Probes or the Adaptive Probe Volumes.

Additional Resources: [LightProbes](/engine/6000.7/script-reference/unityengine/lightprobes.md).

## Examples

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

// This script generates uniform grids of light probes. Add it to a game
// object and use the context menu of the script to update the positions
// of the probes in the associated Light Probe Group.
[RequireComponent(typeof(LightProbeGroup))]
public class ProbePlacement : MonoBehaviour
{
    public uint SizeX = 8;
    public uint SizeY = 4;
    public uint SizeZ = 4;

    [ContextMenu("Update Positions")]
    void Place()
    {
        var positions = new List<Vector3>();
        for (uint x = 0; x < SizeX; x++)
        {
            for (uint y = 0; y < SizeY; y++)
            {
                for (uint z = 0; z < SizeZ; z++)
                {
                    positions.Add(new Vector3(x, y, z));
                }
            }
        }
        gameObject.GetComponent<LightProbeGroup>().probePositions = positions.ToArray();
    }
}
```
