when in the graph, right-click in and open area, make sure “context sensitive” is selected, type “self” there should be an option to get the self reference.
create a variable that is PrimalItem.
set that variable as the self object.
you can now use a Get of that PrimalItem then drag off and access the OwnerInventory from there you can then get the owner class, and hopefully create your widget.
Check out the SCUBA_Shirt_with_Tank class as a reference
PS sorry for the step by step at the top, it obviously looks like you know how to access items, but that was for anyone else that may stumble upon this thread.
