If a TMap containing a struct is created in a custom code class, the properties of the struct do not appear when elements are added to the TMap in the Blueprint editor.
You can add elements to the TMap, but the properties contained in the struct that makes up each element of the TMap do not appear.
The struct properties appear in each element of the TMap.
If you add a property to the class containing the TMap that is the same as the struct in the TMap, then the properties of the struct will appear in each element of the TMap. To see this, open the MyActorComponent.h file in Visual Studio and uncomment the two lines adding a FMyStruct property to the class.
