public static Object Load (string path);



This function will look in Assets/Editor Default Resources/ + path for the resource. If not there, it will try the built-in editor resources by name.

using UnityEngine;
using UnityEditor;

public class LoadExample { [MenuItem("Examples/Load Editor Texture Example")] static void loadExample() { Texture tex = (Texture)EditorGUIUtility.Load("aboutwindow.mainheader"); Debug.Log("Got: " + + " !");

Renderer r = GameObject.Find("Cube").GetComponent<Renderer>(); r.sharedMaterial.mainTexture = tex; } }
