UAssetManager::GetAllReferencersForPackage
#include "Engine/AssetManager.h"
Access: public
Specifiers: static
Description
Finds all packages that reference any of the given packages, recursing up the dependency graph to the given depth.
Caveats & Gotchas
- • Recursion depth is controlled by MaxDepth; passing a large value on a big project walks the full dependency graph and can be slow.
- • OutFoundAssets is a TSet so results are unordered — don't rely on iteration order for UI or reports.
