# ForceLOD(int)

> Disable automatic LOD selection based on camera distance by forcing a specific LOD level, or revert to the default automatic behavior by passing a negative value as parameter.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine](/engine/6000.6/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public void ForceLOD(int index)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The LOD level to use. Passing a negative index value enables automatic LOD selection.

### Remarks

This method specifies explicitly which LOD level Unity should use. You can achieve the same result in a script by disabling the `LODGroup` component and renderers of the unneeded LOD levels, but using the `ForceLOD` method provides slightly better CPU performance. This is relevant if you need to force a particular LOD state only for a few frames. This method lets you avoid storing the original states of the renderers when you force an LOD level.

If you need to force a particular LOD level for a large number of LODGroups for a large number of frames, the alternative approach of disabling the `LODGroup` and renderers might provide better CPU performance.

### Examples

```csharp
using UnityEngine;

public class SampleScript : MonoBehaviour
{
    public bool isHero = false;

    private LODGroup m_LODGroup;

    void Start()
    {
        m_LODGroup = GetComponent<LODGroup>();
    }

    void Update()
    {
        if (!m_LODGroup)
            return;

        // Force LOD to highest quality level (0) when in hero mode
        // Else enable automatic LOD selection (-1).
        m_LODGroup.ForceLOD(isHero ? 0 : -1);
    }
}
```
