Material.Lerp

Description

Интерполирует свойства между двумя материалами.

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.

    public Material material1;

    public float duration = 2.0F;

    void Start() {
        rend = GetComponent<Renderer>();
        rend.material = material1;
    }
    void Update() {
        float lerp = Mathf.PingPong(Time.time, duration) / duration;
        rend.material.Lerp(material1, material2, lerp);
    }
