# ChangeAssetObjectPropertiesEventArgs

> A change of this type indicates that a property of an asset object in memory has changed. This happens for example when Undo.RecordObject is used with an instance of an asset (e.g. Texture ). Note that this only covers changes to asset objects in memory and not changes to assets in the project on disk.
