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


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 = Mathf.PingPong (Time.time, duration) / duration;
renderer.material.Lerp (material1, material2, lerp);
