Material Parameter Collections and Code?

Hi. Just in case someone wonder how directly load de collection. But keep in mind the above warning about cooked content. // Class variable UMaterialParameterCollection* collection; ... // Inside constructor: ... ConstructorHelpers::FObjectFinder<UMaterialParameterCollection> objectType(TEXT("/Game/Project/Materials/MPC_Params")); if (objectType.Succeeded()) { collection = objectType.Object; } ... // when needed UMaterialParameterCollectionInstance * pci = GetWorld()->GetParameterCollection…

This can also be exposed as a uproprerty in the header and assigned in editor.

UPROPERTY(VisibleAnywhere, BlueprintReadWrite, meta = (AllowPrivateAccess = "true"))
UMaterialParameterCollection* collection;
