Android Material Error !

Hi
I'll start with a screenshot:


I'll explain my problem, I make a scene with Unity 5.3, this scene contains a Cornell Box, the simple idea is when I touch the power icon, the light switched from On to Off " all lights is baked in 3ds max + VRay " So I used here switch from Unlit/Texture shader to Mobile/Diffuse shader to looks that lights are off
in Unity editor all done well, but in Samsung Android the Shader looks one color like missing materials

Here is my button power code:

Code (JavaScript):

1. var spriteOff : Sprite;
2. var spriteOn : Sprite;
3.  
4. var shader1 : Shader;
5. var shader2 : Shader;
6.  
7. var parent : GameObject;
8.  
9. function Update()
10. {
11.       shader1 = Shader.Find("Mobile/Diffuse");
12.      shader2 = Shader.Find("Unlit/Texture");
13. }
14.    
15. function OnMouseDown()
16. {
17.  
18. var renderers:Renderer[] = parent.GetComponentsInChildren.<Renderer>() as Renderer[];
19. for (var child : Renderer in renderers )
20.      {
21.         if (child.material.shader == shader1)
22.             child.material.shader = shader2;
23.         else
24.             child.material.shader = shader1;
25.      }
26. if(GetComponent(SpriteRenderer).sprite == spriteOn)
27.     GetComponent(SpriteRenderer).sprite = spriteOff;
28.     else
29.     GetComponent(SpriteRenderer).sprite = spriteOn;
30.  
31. }
32.  

How can I solve that ?

 

no answer !

 

As per the documentation here:

Sounds like the cause. To fix it, make sure you have a hard reference to the shader - instead of using 'Shader.Find', you should 'connect' the correct shaders to shader1 and shader2 in the inspector! This way, Unity will know for sure that you want that shader included in your project.

When you use Shader.Find, Unity can't guess which shaders you want to include in your game (because you can pass any string in to Shader.Find. So Unity ends up excluding any shader in your project that isn't directly referenced by any object.

 

Great Explain Thanks Prodigga
