Here is a personal piece.
Lake Saimaa rendered in Unreal Engine 5.
Getting the extremely high poly foliage behave has been challenge. LODs have transitions and imperfections and Nanite even with preserve area and several tweaks still don't look right. The birch threes are couple of million trees per piece, still ran okayish and I wasn't making a game here.
I ended up getting best result with Hardware Raytracing turned off.
Didn't end up using antialiasing, just TSR with some screenpercentage and game overrides.
No AI whatsoever was used in this, everything hand made.
