Unity Tree transparency

Hello! I made an application with trees, created by Unity Tree Creator. I want filter some trees, so I replace shader and color to make transparent trees. It works in debug and standalone version too. Here's the code:

 private void SetTransparent(GameObject g)
     {
         for (int i = 0; i < g.renderer.materials.Length; i++)
         {
             g.renderer.materials[i].shader = Shader.Find("Transparent/Diffuse");
             g.renderer.materials[i].SetColor("_Color", new Color(1, 1, 1, 0.1f));
         }
         for (int i = 0; i < g.transform.childCount; i++)
             SetTransparent(g.transform.GetChild(i).gameObject);
     }

And the result:

I have an invert method to restore original shader and material color:

 private void RevertTransparent(GameObject g)
 {
     for (int i = 0; i < g.renderer.materials.Length; i++)
     {
         if (g.renderer.materials[i].name == "Optimized Bark Material (Instance)")
             g.renderer.materials[i].shader = 
                            Shader.Find("Nature/Tree Creator Bark");
         else if (g.renderer.materials[i].name == 
                            "Optimized Leaf Material (Instance)")
             g.renderer.materials[i].shader = 
                            Shader.Find("Nature/Tree Creator Leaves Fast");
         else
                 g.renderer.materials[i].shader = Shader.Find("Default/Diffuse");
             g.renderer.materials[i].SetColor("_Color", new Color(1,1,1));
     }
     for (int i = 0; i < g.transform.childCount; i++)
         SetTransparent(g.transform.GetChild(i).gameObject);
 }

And the restoring works only in debug mode in unity editor, in builded version this happens:

Any idea how to properly change textures in standalone version too?
