Change emission brigthness in standard shader with script - standalone player

I can change emission brigthness in play mode, but not in windows standalone player:

Code (CSharp):

1.   using UnityEngine;
2.   using System.Collections;
3.  
4.   public class Load : MonoBehaviour
5.   {
6.  
7.      private int brojac;
8.      private GameObject clone;
9.      private bool kontrola;
10.      private Material mat;
11.      private Renderer rend;
12.      public GameObject[] tileObjects;
13.  
14.  
15.      void Start ()
16.      {
17.        brojac = 0;
18.        kontrola = true;
19.      }
20.  
21.  
22.      void Update ()
23.      {
24.  
25.        if (Input.GetMouseButtonDown (0) && kontrola) {
26.          load_model ();
27.        }
28.      
29.        if (clone != null && !kontrola) {
30.      
31.          if (Input.GetMouseButtonDown (1)) {
32.            Destroy ();
33.          }
34.  
35.          if (Input.GetKey ("k")) {
36.            rend.material.SetColor ("_EmissionColor", Color.red * 1.5f);
37.            //DynamicGI.SetEmissive (rend, Color.red);
38.            DynamicGI.UpdateMaterials (rend);
39.          }
40.          if (Input.GetKey ("l")) {
41.            rend.material.SetColor ("_EmissionColor", Color.black);
42.            //DynamicGI.SetEmissive (rend, Color.black);
43.            DynamicGI.UpdateMaterials (rend);
44.          }
45.        
46.  
47.        }
48.  
49.      }
50.  
51.  
52.      void load_model ()
53.      {
54.  
55.        clone = Instantiate (tileObjects [brojac], new Vector3 (0, 0, 0), Quaternion.identity) as GameObject;
56.        clone.name = "Lamp";
57.        rend = clone.GetComponent<Renderer> ();
58.        rend.material.EnableKeyword ("_EMISSION");
59.        kontrola = false;
60.  
61.      }
62.  
63.  
64.      void Destroy ()
65.      {
66.        Destroy (clone, 0.5f);
67.        brojac++;
68.        if (brojac == 15)
69.          brojac = 0;
70.        kontrola = true;
71.      }
72.  
73.   }
74.  

 

SOLUTION

Edit - Project Settings - Graphics - Include Standard Shaders

 

Where do you see this option? Is this something new? I am using Unity 5.2.3. There is no option for this, but I can set the emission color anyways for the player.

All my 15 objects are prefabs.
Please post your solution...

 

I have a material in the Resources folder using the standard shader. So then I think, for my situation, the Standard shader will be automatically be included because it is used for something in the Resources folder. That might explain why I don't need to add it the list.
