# Lerp(Material, Material, float)

> Interpolate properties between two materials.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine](/engine/6000.5/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public void Lerp(Material start, Material end, float t)
```

### Parameters

**** (\[Material]\(/engine/6000.5/script-reference/unityengine/material)): **** (\[Material]\(/engine/6000.5/script-reference/unityengine/material)): **** (\[float]\(https\://learn.microsoft.com/dotnet/api/system.single)): 

### Remarks

Makes all color and float values of a material be interpolated from `start` to `end`, based on `t`.

When `t` is 0, all values are taken from `start`.

When `t` is 1, all values are taken from `end`.

Most often you want the materials that are interpolated between to be the same (use the same shaders and textures) except for colors and floats. Then you use Lerp to blend between them.

### Examples

```csharp
using UnityEngine;

public class Example : MonoBehaviour
{
    // Blends between two materials

    Material material1;
    Material material2;
    float duration = 2.0f;
    Renderer rend;

    void Start()
    {
        rend = GetComponent<Renderer> ();

        // At start, use the first material
        rend.material = material1;
    }

    void Update()
    {
        // ping-pong between the materials over the duration
        float lerp = Mathf.PingPong(Time.time, duration) / duration;
        rend.material.Lerp(material1, material2, lerp);
    }
}
```
