Hi, @High500
Thanks for your reply, I double-checked Arran Langmead’s PCG presentation in GDC. At the end of the video, he said the stuff he showed is editor only, and they do have game involvement which can ship the empty level and completely generate it when the player loads the game.
While writing this, I checked again the " New Tools for Building Photoreal Worlds in Unreal Engine 5.2 | GDC 2023" video from Unreal about the large world prototype around 12:40. He said, “The hierarchical generation concept is to be implemented natively in the framework in the very near future.”
So yeah, I think you are correct.
LOL, I looked too closely at the demo to ignore the sentence. I also won’t use it in any game right now, just experimenting, thanks for the advice.
