# treeCrossFadeLength

> Total distance delta that trees will use to transition from billboard orientation to mesh orientation.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.3/script-reference/unityengine.md)
* **Assembly:** UnityEngine.TerrainModule

```csharp
public float treeCrossFadeLength { get; set; }
```

### Remarks

Decreasing this value makes the transition happen faster. Setting it to 0 will produce a visible pop when switching from mesh to billboard representation.

### Examples

```csharp
using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        Terrain.activeTerrain.treeCrossFadeLength = 20;
    }
}
```
