There's a running joke on my Discord server, that the answer to most #UnrealEngine questions is "did you see how Lyra handles this?" because the Lyra project is so completely full of good examples. UI, multiplayer, editor tools it's all there.

Lyra Starter Game in UE Game Samples - UE Marketplace

Lyra Starter Game is a sample gameplay project built alongside UE5 development to serve as an excellent starting point for creating new games. We plan to continue to upgrade it with future releases to demonstrate our latest best practices.

@_benui Digging through Lyra is always a ton of fun.

I do find myself scratching my head from time to time asking "Why is this complexity warranted?"

Levels of abstraction that the Lyra leads introduce into their solutions is sometimes astronomical!

But then, I dig further and eventually start to see the "why" in all the indirection.

I think more longform docs around Lyra architecture would be wonderful, but of course... one more thing for Epic to maintain 😅

@aaronransley I think it's partly to show how you might do things like that for a much larger AAA-game. For Lyra it's overkill but it's designed to work on something 10x as big (i.e. Fortnite).
