UAssetManager::RegisterSpecificPrimaryAsset
#include "Engine/AssetManager.h"
Access: public
Specifiers: virtual
Description
Manually registers a new or updated Primary Asset outside of the normal directory-scan flow. Returns true if registration succeeded.
Caveats & Gotchas
- • Intended for assets that exist outside the configured Primary Asset scan directories (e.g. dynamically generated or runtime-created assets) — assets under normal scan paths get registered automatically and don't need this.
- • Not const, since it mutates the Asset Manager's internal Primary Asset registry — calling it from a const context requires going through a non-const accessor.
- • Does not itself check DoesAssetMatchSearchRules; the caller is responsible for ensuring the asset data and ID are consistent before registering.
