[Unity] Assetbundle Shader 遺失的解決方案

物件打包成 AssetBundle 後有的物件上的材質的shader 會 lost 變一塊紫色

//assetbundle後shader會lost的處理
gameObject.renderer.material.shader =  Shader.Find(gameObject.renderer.material.shader.name); 

或是

    using UnityEngine;
    using System.Collections;
    public class ApplyShader : MonoBehaviour 
    {
        private Material[] thisMaterial;
        private string[] shaders;
        void Start () {
            thisMaterial = this.renderer.sharedMaterials;             
            shaders =  new string[thisMaterial.Length];
            for( int i = 0; i < thisMaterial.Length; i++){
                shaders[i] = thisMaterial[i].shader.name;
            }    

            for( int i = 0; i < thisMaterial.Length; i++){
                thisMaterial[i].shader = Shader.Find(shaders[i]);  
            }
        }
    }
