UAssetManager::GetPrimaryAssetLoadSet
#include "Engine/AssetManager.h"
Access: public
Specifiers: const
Description
Fills OutAssetLoadSet with the unique object paths that would need to be loaded for a primary asset under the given bundle list, without actually loading them.
Caveats & Gotchas
- • The header explicitly recommends using GetPrimaryAssetLoadList instead — this overload exists only for backward compatibility and creates an extra TSet allocation.
- • Returns false without modifying OutAssetLoadSet if PrimaryAssetId isn't a recognized primary asset.
