Note: User posted code linked to spawn actor on linked URL. Code is located below:

ASpawner::ASpawner()

{ Spawned = nullptr; }

void ASpawner::BeginPlay()
{
Spawned = GetWorld()->SpawnActor<AActor>(SpawnedClass);
for (UActorComponent* MeshActorComponent : Spawned->GetComponentsByClass(UStaticMeshComponent::StaticClass()))

{ UStaticMeshComponent *Mesh = Cast<UStaticMeshComponent>(MeshActorComponent); check(Mesh); Mesh->SetMaterial(0, MaterialToSet); }

PrintMeshMaterials();
Spawned->SetActorLabel(TEXT("Spawned Actor with Label"));
PrintMeshMaterials();
}

void ASpawner::PrintMeshMaterials()
{
for (UActorComponent* MeshActorComponent : Spawned->GetComponentsByClass(UStaticMeshComponent::StaticClass()))

{ UStaticMeshComponent *Mesh = Cast<UStaticMeshComponent>(MeshActorComponent); check(Mesh); UMaterialInterface* Material = Mesh->GetMaterial(0); GEngine->AddOnScreenDebugMessage(-1, 1000.0f, Material == MaterialToSet ? FColor::Green : FColor::Red, Material->GetName()); }
