A change of this type indicates that an asset object has been created. This happens for example when Undo.RegisterCreatedObjectUndo is used with an instance of an asset (e.g. Texture).
| guid | The GUID of the new asset. | 
| instanceId | The instance ID of the modified asset. | 
| scene | The Scene that contains the new asset. This is usually an invalid scene unless the asset is explicitly associated in a scene (e.g. RenderSettings). | 
| CreateAssetObjectEventArgs | Constructs a new instance. |
