Then, open a blueprint (like the level blueprint for example).
Add a Custom Event (a function, macro or even something like a ForEach node would work as well, in the next steps I have assume you’ve created a custom event).
Add a parameter (an ‘input’) to the event.
Change the parameter type to a struct (I used ‘Anchors’ for example, but any struct will do).
Rightclick on the parameter in the event and click on ‘Split Struct Pin’ (see screenshot).
