In this tutorial, we take a look at the three ways in which you can reference an instance of a widget blueprint in the scene graph system, so you can gain access to the MVVM and data fields. This might change in the future, but these are the three main ways as of November 2026; each way has its pros and cons. Previously, we had suspected that the tagging system might not be working as expected, but we confirmed the tagging system is working, so it is a method as valid as outliner parenting.
