At one point, UEnum was not supported but was going to be in the future. I have one in my project which is not showing up in the IDE. Are they still not supported?
Reflection of enums (via UENUM()) is supported. The catch is that they show up in the IDE only if they are referenced (even if indirectly) by a class that's also reflected (annotated with UCLASS()).
I just had a thought: is there a way to declare a UEnum in SK and then use it with C++/BP?
