Yes, I am talking about how Unreal seems to handle data inheritance.
I don’t care if it is a flag or a diff between two dictionaries of serialized properties, both would work just fine and can disappear when packaging the game if the overhead bothers you.
The problem is that this information doesn’t seem to be serialized as of now, which can create silent bugs during production and iterations on those properties.
The “override” information on properties is just a visual feedback in the editor views (yellow arrow) and will not prevent the situation I described to happen (if a child previously overriden has its value becoming equal to its parent, the override information disappears).
