Hi,

I am beginner and I am trying to understand how to use PostEditChangeChainProperty function. I have the following USTRUCT in my header:

USTRUCT()
struct FMyStructTest
{
	GENERATED_BODY()

		UPROPERTY(EditAnywhere)
			bool Struct_Foo;
		UPROPERTY(EditAnywhere)
			bool Struct_Bar;

		FMyStructTest()
	{
		Struct_Foo= true;
		Struct_Bar = true;
	}
};

	UPROPERTY(EditAnywhere, Category = Test)
		TArray<FMyStructTest> TestStruct;

I also have functions to build a UProceduralMeshComponent. I would like to popup specific UProceduralMeshComponent on details panel using my USTRUCT. For this I am using PostEditChangeChainProperty declared in my .h file as follow:

Void PostEditChangeChainProperty(FPropertyChangedChainEvent& PropertyChangedEvent);

And I made the following code on my cpp:

void Atest::PostEditChangeChainProperty(
	FPropertyChangedChainEvent& PropertyChangedEvent)
{
	Super::PostEditChangeChainProperty(PropertyChangedEvent);

	const FName Tail = PropertyChangedEvent.PropertyChain.GetTail()->GetValue()->GetFName();

	UE_LOG(LogTemp, Warning, TEXT("Structure Modify: %s"), *Tail.ToString());


	if (PropertyName == FName(TEXT("TestStruct"))) {
		TerrainFace1(Vertices, Traingles) ; 
		UE_LOG(LogTemp, Warning, TEXT("Struct_Foo"));
	}

	if (PropertyName == FName(TEXT("TestStruct"))) {
		TerrainFace2(Vertices, Traingles);
		UE_LOG(LogTemp, Warning, TEXT("Struct_Bar"));
	}
}

However, UProceduralMeshComponent are not updated.

Could you please provide me some guidance.

Thank you.
