Access: public
Specifiers: staticUFUNCTIONBlueprintCallable
Description
Duplicates an object to a new instance, copying its property values into a fresh UObject with the given outer and name.
Caveats & Gotchas
- • Only compiled with WITH_EDITOR — this node is not available in packaged/runtime builds; it's an editor-tooling utility, not a gameplay spawn/duplicate function.
- • Returns null if the duplication fails (e.g. invalid SourceObject).
- • This is a shallow wrapper around the engine's StaticDuplicateObject — it does not spawn actors into a world or trigger BeginPlay; for runtime actor duplication use SpawnActor or similar.
