Scene Fusion syncs landscape creation, deletion, properties, splines and changes made by the painting tools.
Currently Scene Fusion only syncs changes made to the blueprints that are created from actors and components. Blueprint creation and deletion is not synced. To sync a blueprint, you need to either add an instance of the blueprint to the level or open the blueprint while you are in a session.
Scene Fusion syncs the blueprint default objects, which are the actors and components making up the blueprint. Both the hierarchy and the properties will be synced.
Scene Fusion syncs the blueprint graphs, including the event graph, construction script, functions, macros, variables, event dispatchers and local variables. Creation, deletion and modification will be synced. Changes made to the nodes and links on the Graph editor will also be synced. Nodes that reference missing classes or functions will be replaced with a custom Scene Fusion node that contains information about the missing data. Warnings will also be added to the "Missing Asset" window when missing classes or functions are detected. The warning node will be replaced with the proper node after you include the missing class and functions and trigger a recompile. This detection works both in and outside of Scene Fusion sessions.
