In this talk, you'll get a look at how we battle-tested Lumen, Nanite, Virtual Shadow Maps (VSM), and other Unreal Engine 5 systems while developing Fortnite Battle Royale Chapter 4, and how this collaboration with the Fortnite team improved Unreal Engine for all developers. We'll dissect how UE5's systems enhanced visual quality in Fortnite, how we adapted the features to best serve the game, and how we solved some of the specific issues that we came up against while maintaining a streamlined production pipeline. In the second half of the talk, we'll look at some of the key improvements we've made to Lumen, Nanite, and VSM in UE5. We'll explore some of the research and development that went into making those updates, including the challenges we were looking to overcome, and how the solutions to them will benefit the look, performance (and in some cases, the budget) for your game.
