I’m investigating these functions, but with my short knowledge of c++, I don’t know where to go further.

  • SKismetDebugTreeView::OnGetChildren()
  • FSelfWatchLineItem::GatherChildren()
  • FKismetDebugUtilities::GetDebugInfoInternal()
  • FPropertyInstanceInfo::FindOrMake()
  • FPropertyInstanceInfo::PopulateChildren()

With long length of container, like TArray or TMap, I can see the repeating of FPropertyInstanceInfo::FindOrMake() and FPropertyInstanceInfo::PopulateChildren(). Then hitch is appeared.
