The base Asset Manager class that is included in the Engine provides basic management functionality, but can be extended to suit project-specific needs. The Asset Manager object is a singleton that manages discovery and loading of Primary Assets. In order to make a Secondary Asset into a Primary Asset, the GetPrimaryAssetId function for its class must be overridden to return a valid FPrimaryAssetId structure. By default, only UWorld Assets (levels) are Primary all other Assets are Secondary. Secondary Assets are not handled directly by the Asset Manager, but instead are loaded automatically by the Engine in response to being referenced or used by Primary Assets. In order to designate Assets made from a specific UObject class as Primary Assets, override GetPrimaryAssetId to return a valid FPrimaryAssetId structure. Primary Assets can be manipulated directly by the Asset Manager via their Primary Asset ID, which is obtained by calling GetPrimaryAssetId. It also provides a set of tools to help audit disk and memory usage, giving you the information you need to optimize the organization of your Assets for cooking and chunking when deploying your game.Ĭonceptually, the Asset management system in Unreal Engine 4 breaks all Assets into two types: Primary Assets and Secondary Assets. It provides a framework for managing Assets that can divide content into chunks that make sense in the context of your project, without losing the advantages of Unreal Engine 4's loose package architecture.

The Asset Manager is a unique, global object that exists in the Editor as well as in packaged games, and can be overridden and customized for any project.

For these cases, the Asset Manager can help.

However, there are cases where a developer might want more precise control over when and how Assets are discovered, loaded, and audited. Unreal Engine 4 handles Asset loading and unloading automatically, which relieves developers of the burden of coding systems to tell the Engine exactly when each asset is going to be needed.
