Umm, its not that you cant nest arrays in unreal, you can do whatever you want through structs, its that they dont allow to nest their Templated arrays, like TArray and TMap and other Unreal templated arrays.
I just wanted to create a two dimensional array to store an id and strings, like this:
TMap<FName,TArray<FString>> Test;
But the HeaderTool doesnt allow that, so I will probably use a different solution completely or I will make a struct, like:
USTRUCT(BlueprintType)
struct FStringList
{
GENERATED_BODY()
UPROPERTY(EditAnywhere, BlueprintReadOnly)
TArray<FString> Items;
};
//then the variable:
TMap<FName,FStringList> Test;
