Unity Script Reference – Material.Lerp

Material.Lerp

function Lerp (start : Material, end : Material, t : float) : void

Description

Interpolate properties between two materials.

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.

// Blends between two materials

var material1 : Material;
var material2 : Material;
var duration = 2.0;

function Start () {
    // At start, use the first material
    renderer.material = material1;
}

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