UAssetManager::RefreshPrimaryAssetDirectory
#include "Engine/AssetManager.h"
Access: public
Specifiers: virtual
Description
Refreshes the entire set of primary asset data, useful in the editor after assets have changed dramatically.
Caveats & Gotchas
- • Without bForceRefresh=true, it only rescans if the manager detects something changed, so asset edits made outside the normal editor workflow (e.g. via script) may be missed.
- • Effectively redoes primary asset type scanning and can be slow on large projects — avoid calling it every frame or in tight loops.
