Is there a way to get a SkeletalMesh from another actor or SkeletalMeshComponent and set it to mine?
What I’m trying to achieve and what I’ve tried:
I have a WeaponPickup class with WeaponClass property. When player collects pickup, weapon of given WeaponClass is spawned and given to the player. That works. The problem is that I’d like WeaponPickup look like actual weapon, because player want to see what they are about to pick up 
I tried duplicating weapon’s mesh from weapon CDO into WeaponPickup, but results in the assertion failure when Play in editor:
// I call this in the PostInitializeComponents and when the WeaponClass property is changed by editor
void AWeaponPickup::ReinitHeldWeapon()
{
ABaseWeapon* weaponCDO = WeaponClass != nullptr ? Cast<ABaseWeapon>(WeaponClass->GetDefaultObject()) : nullptr;
if (!weaponCDO)
return;
USkeletalMesh* mesh = DuplicateObject(weaponCDO->GetMesh(), meshComponent);
USkeletalMeshComponent* meshComponent = GetPickupSkeletalMesh();
meshComponent->SetSkeletalMesh(mesh);
// Ensure condition failed: !(bDuplicateForPIE && DupObjectInfo.DuplicatedObject->HasAnyFlags(RF_Standalone)) [File:D:/Build/++UE4+Licensee/Sync/Engine/Source/Runtime/CoreUObject/Private/UObject/UObjectGlobals.cpp] [Line: 2103]
There is a corresponding UE code:
/Engine/Source/Runtime/CoreUObject/Private/UObject/UObjectGlobals.cpp
UObject* StaticDuplicateObjectEx( FObjectDuplicationParameters& Parameters )
{
// ...
bool bDuplicateForPIE = (Parameters.PortFlags & PPF_DuplicateForPIE) != 0;
// Any PIE duplicated object that has the standalone flag is a potential garbage collection issue
ensure(!(bDuplicateForPIE && DupObjectInfo.DuplicatedObject->HasAnyFlags(RF_Standalone)));
So, it looks like I misuse DuplicateObject. Is there some way I can do such an assignment correctly?
Thanks in advance!
