UKismetSystemLibrary::SetEditorProperty
#include "Kismet/KismetSystemLibrary.h"
Access: public
Specifiers: staticBlueprintCallableCustomThunkWITH_EDITOR
Description
Sets the value of a named property on the given object by name, for use in editor utility scripts and Blutilities.
Caveats & Gotchas
- • Editor-only: compiled inside WITH_EDITOR, so it is unavailable in packaged/runtime builds.
- • Setting ChangeNotifyMode incorrectly can skip PostEditChangeProperty notifications that other editor systems (e.g. construction scripts, detail panel refresh) depend on.
- • This does not automatically wrap the change in an undo transaction — call BeginTransaction and TransactObject first if the edit should be undoable.
