Interpolate properties between two materials.

  • Namespace: UnityEngine
  • Assembly: UnityEngine.CoreModule
public void Lerp(Material start, Material end, float t)

Parameters

start

Material

end

Material

t

float

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

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);    }}
