Set Alpha to Transparency in Runtime with a script

Hello!

I was wondering if there is a way to change a texture's alpha to transparent (imported in runtime).
Basically, I am making a system to change textures, and I want it so that when applying a texture with Alpha, set the alpha to transparent, right now I see it black. I already have the texture system. I have searched a little bit on Google and I can only find things about setting Alpha to Transparency but not in runtime (I can only find for editor). Which I already know.


Thank you!

 

For a bit more info:

The script uses a simple.
Texture newTexture;

Which I then search in a folder for a certain texture and set it.
And I just basically want to set Alpha to transparency before this:

Renderer rend = gameObject.GetComponent<Renderer> ();
rend.material.mainTexture = newTexture;

In the editor, it would be like that:

But I want to do it in a script (C# if possible).

 

Ok, found it after a lot of searches, I thought I needed to modify the texture, but it's the material/shader that matters.

Here's the code:

Code (CSharp):

1. Renderer rend = gameObject.GetComponent<Renderer> ();
2. Shader shader = Shader.Find("Transparent/Diffuse");
3. rend.material.shader = shader;
