How to query property flags from C# for each shader property

I have been trying to search the API and Google and so far haven't come up with anything.

The problem seems simple enough. From a C# script I want to check whether the shader on a given material has a certain flag (e.g., PerRendererData). This seems to be exactly what I want:

https://docs.unity3d.com/ScriptReference/MaterialProperty.PropFlags.PerRendererData.html

However, I am not sure how to create a MaterialProperty as that appears to only come from a ShaderGUI implementation which would only run when selected in the inspector. I want a separate editor script that can enumerate all materials in the project at the same time and is run from a menu item.

I can create a SerializedObject from a Material reference as such:

var serializedMaterial = new SerializedObject(material);

But I am still not sure how to convert the properties from a SerializedProperty to a MaterialProperty or if that's even possible.

Obviously I can get creative and just get the shader asset path and parse the shader text myself, but I was hoping there would be a cleaner way to do this with existing API. I feel like I am missing something obvious. The ShaderUtil class also doesn't seem to support this.

Any suggestions? Thanks!

EDIT: After looking at ShaderUtil more closely, it looks like this function is exactly what I want:

internal static extern MaterialProperty GetMaterialProperty(
UnityEngine.Object[] mats,
string name);

Only, it's internal. I can probably call it through reflection, but I still hold out hope for a much cleaner way.

 

It’s exposed as a public static here:
https://docs.unity3d.com/ScriptReference/MaterialEditor.GetMaterialProperties.html

 

It seems so obvious now - not sure how I missed that (but I did say I am probably missing something obvious, haha). Thanks!
