Using Enum Value In Property Meta Data Does Not Compile

Out of curiosity, have you tried using removing the “class” modifier from your enum (thus making it effectively just an int in disguise)? Enum Classes are a C++11 thing that enforce type safety so I could see that causing issues.

You are right, it works like this now:

UENUM()
enum EUnits {
	None = 0,
	Percentage = 1,
	Seconds = 2
};

I then had to change all the enum members that I had to TEnumAsBytey but thats not a big deal.
