Accessing Shader Graph's properties from C# script

Hi. I'm trying to access properties of Shader Graph via C# Script.

I've created a PBR shader graph named "TV_screen_graph"
I've created two properites : emission_intensity(vector 1) and movie_texture(texture 2D asset) in my shader graph.
I've created a material named TV_screen_mat and chose the TV_screen_graph
I've assigned the TV_screen_mat to my mesh

Now, I want to control the emission_intensity and start the movie_texture to play via C# script

I've tried

Code (CSharp):

1.     void Start () {
2.  
3.         Renderer r = GetComponent<Renderer>();
4.         MovieTexture movie = (MovieTexture)r.material
5.  
6.         movie.Play();
7.     }
8.    

to play the movie texture, it failed, and I know things don't work that way with shader graph material but I have no idea how to access the properties from shader graph.

Someone pls help me. Thanks.

 

Play movie.

Change emission.

What I am saying is I am using shader graph which is a new feature included in Unity 2018. Not a standard material.
What I want to do is I want to play the movie texture that I imported into shader graph. Not on the camera background as the doc says.
I want to change the emission intensity of the Shader Graph with C# script, not the emission intensity of the standard material.

I need to know how to access the properties of the Shader Graph which is imported into material via C# Script.

Thanks.

Open shader graph where you name the property, there is a textbox saying "Reference" name your property there. Shader graph will rename it with underscores. Use this name in your script
