Question Create a material from shader graph asset in editor script

How can I create a material in an editor script in much the same way as I would from a shader asset?

Code (CSharp):

1. Shader myShader = (Shader)AssetDatabase.LoadAssetAtPath(shaderPath, typeof(Shader));
2.  
3. Material mat = new Material(myshader);
4.  
5. Material mat2 = new Material( ?? myshader.shadergraph)

 

You can do that exactly like if it's a shader asset, just as you said

Code (CSharp):

1. Material material = null;
2. Shader shader = Resources.Load<Shader>("MyShaderGraphAsset");
3. if (shader != null)
4. {
5.     material = new Material(shader);
6. }

 

This will fail unless the shader graph is in a resources folder. From the manual:

"Loads the asset of the requested type stored at path in a Resources folder using a generic parameter type filter of type T."

I need to load it from a specific path that is not in a Resources folder and I don't want it to be included in builds.

 

Try something like this, works for me!

Code (CSharp):

1.                     // Create a new material with the same properties as the imported material
2.                     Material newMaterial = null;
3.  
4.                     defaultShader = Shader.Find("Shader Graphs/SphereMask");
5.  
6.                     if (defaultShader != null)
7.                     {
8.                         newMaterial = new Material(defaultShader);
9.                     }
10.                     else
11.                     {
12.                         Debug.LogError("Couldn't load shader");
13.                     }
