Are you sure you’re not simply looking for the tMap:
It allows for association: Enumerator → Skeletal Mesh, for example. Maps and Sets only sport unique keys by default.
How can I loop this logic to cycle through every Enum element in the Enum variable
You can literally loop through any enumerator:
Search for ForEach YourEnumerator
Not gonna lie, not entirely sure what the end goal here is, so my suggestion might be off.
what connects to the -1/1 reroute pin
Index cycling, most likely. You ++ / -- to pull next / previous element from the enumerator - just an int here. That’d be useful if you had something like a weapon select wheel (like GTA) and wanted to cycle through available choices.
I feel like the person did not realise one can loop through enums or add bytes:

But, perhaps, the rest of the script needed integers.
