[UPROPERTY](Programming/UnrealArchitecture/Reference/Properties)()
FString ValuePropertyName
Value property name, in case a map is being indexed. ie. The path Var.Var_Value[0] will populate ValuePropertyName with "Var" This is needed because sometimes the value's property name will differ from the name before. For example a map property named Test_1 will generate the following path: Test_1.Test_Value[0]
