Bug Having a custom Transform inspector prevent recording transform modifications

The menu entries associated to recording ("Add key", "Remove key", etc.) are added to menus for property fields. In your custom inspector, you will need to draw fields using the PropertyField method (in EditorGUI or EditorGUILayout).

For example, here's a component with a custom inspector that uses the PropertyField method:

Code (CSharp):

1. public class TestComponent : MonoBehaviour
2. {
3.     public float value;
4. }
5.  
6. [CustomEditor(typeof(TestComponent))]
7. public class TestEditor : Editor
8. {
9.     public override void OnInspectorGUI()
10.     {
11.         SerializedProperty property = serializedObject.FindProperty(nameof(TestComponent.value));
12.         EditorGUILayout.PropertyField(property);
13.  
14.         serializedObject.ApplyModifiedProperties();
15.     }
16. }

When recording is enabled in Timeline, I get the recording menu entries if I right-click on a property:
