I been wondering, about Blue printing and nodes if all spot on, but just imagine, if no one ever have to do it, create a auto node within the game engine in the future, so when after sculpt landscape, and then adding trees folage all the nodes are automatic, and it does it correctly.
So all have to do is just create Games, have an open mind, could be researched, maybe UE5 or UE6, could be an more advanced, for the game engine to handle that sort of juice.
