UAssetManager::SearchAssetRegistryPaths

function Engine Since 4.22

#include "Engine/AssetManager.h"

Access: public Specifiers: virtualconst

Description

Helper that searches the asset registry for AssetData matching the given FAssetManagerSearchRules, combining directory scope, wildcard patterns, and base class filtering. Returns the number of matches found.

Caveats & Gotchas

• Rules.AssetScanPaths directories must already have been scanned by the asset registry (via ScanPathsSynchronous or a prior full scan) or matching assets simply won't be found, with no error raised.
• Rules.bHasBlueprintClasses must be set correctly to match Blueprint assets — it changes how the base class filter is applied against the ParentClass tag rather than the asset's own class.
