Shader not found in my application after build

Hi everyone,

I'm currently stucking on something relative to shaders.

In my scene, I'm adding a shader "Unlit/Transparent" (the one Unity is giving through the editor) to one of my cube (it's for a test) thanks to this script :

myCube.renderer.material.shader = Shader.Find("Unlit/Transparent");
myCube.renderer.material.mainTexture = Resources.Load(myImage) as Texture2D;

It works fine in the Unity Editor but when I'm lauching my built-in appplication, I'm having an error : my shader is not found.

I'm guessing it's a build settings problem (my shader is not exported ?).

Is anybody knowing what's going on ?

Any help would be appreciated. Thanks.

Regards.

From the reference:

When building a player, a shader will only be included if it is assigned to a material that is used in any scene or if the shader is placed in a "Resources" folder.
