PropertyBase matchName attribute app.project.item(index).layer(index).property(name).matchName Description The PropertyBase matchName attribute is a special name for the property used to build unique naming paths. This name helps to identify that the property is part of a unique classification. Every property has a unique matchName identifier. MatchNames are meant to be stable from version to version regardless of its "name" in the user interface or any changes to the application. You can't see matchNames directly through the user interface. But you can refer to them through scripting and sample them via this attribute. Note: Unlike names, matchNames do not change based on the language of the After Effects user interface (English/ French/German/Japanese). Using Help Back 153
