public void Lerp(Material start, Material end, float t);


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.

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); } }
