UE6's direction is settled
Unreal Engine 6 merges UE5 and UEFN into a single engine, and its new gameplay framework, Scene Graph, is built from scratch on Verse. Actors and Blueprints are fully supported in UE6 Early Access (targeted for the end of 2027) and the initial releases; deprecation waits until Scene Graph is mature enough. That window is just about long enough to learn the language properly.
