In UE4 when you double click on a a Datasmith Scene it opens us the Dataprep window and allows you to add/remove/and edit the nodes. In UE5 when you double click on a Datasmith Scene it only shows “Import Settings” and “Datasmith.”
How do I get to this node editor graph for datasmith scenes in UE 5?
Where does the UE4 screenshot comes from.
It is look like an old version of UE4 when the dataprep was not fully complete.
