How convert Legacy animations to the new System

If you need to convert Legacy animations to the new system, specifically to work around this problem with Materials and be able to edit the animations in the new Animation Window :

You can use this code to covert those animations:

Code (csharp):

1.  
2. using UnityEngine;
3. using UnityEditor;
4. using System.Collections;
5.  
6. public class AnimationConverter : EditorWindow {
7.  
8.  
9.     AnimationClip target;
10.     SerializedProperty animationType;
11.  
12.     [MenuItem("Window/AnimationConverter")]
13.     static void OpenWindow()
14.     {
15.         // Get existing open window or if none, make a new one:
16.         EditorWindow.GetWindow(typeof(AnimationConverter));
17.  
18.     }
19.  
20.     void OnGUI()
21.     {
22.         target = EditorGUILayout.ObjectField("Target", target, typeof(AnimationClip), true) as AnimationClip;
23.  
24.         if (GUILayout.Button("Convert"))
25.         {
26.             SerializedObject serializedObject = new SerializedObject(target);
27.             animationType = serializedObject.FindProperty("m_AnimationType");
28.             animationType.intValue = 2;
29.             serializedObject.ApplyModifiedProperties();
30.      
31.  
32.             EditorCurveBinding[]  allCurves = AnimationUtility.GetCurveBindings (target);
33.  
34.             foreach(var data in allCurves)
35.             {
36.                 Debug.Log ("path" + data.path);
37.                 Debug.Log ("propertyName" + data.propertyName);
38.                 Debug.Log ("type" + data.type);
39.  
40.                 if(data.type == typeof(UnityEngine.Material))
41.                 {
42.                     AnimationCurve curve = AnimationUtility.GetEditorCurve(target, data);
43.  
44.                     EditorCurveBinding newBindings = new EditorCurveBinding();
45.                     newBindings.path = data.path;
46.                     newBindings.propertyName = "material." + data.propertyName;
47.                     newBindings.type = typeof(UnityEngine.MeshRenderer);
48.  
49.                     AnimationUtility.SetEditorCurve(target, newBindings, curve);
50.                 }
51.  
52.                 AnimationUtility.SetEditorCurve(target, data, null);
53.  
54.             }
55.         }
56.     }
57. }
