Nanite Geometry is a micro polygon geometry system implemented in Unreal Engine 5. Thanks to it, developers can break the polygons from a game into unlimited parts. In addition, it allows you to import better-quality assets. Even photogrammetric scans with millions of polygons will not affect the fps rate in your game. That is possible because Nanite only processes the details players can see. Thus, it reduces the consumption of what does not appear on the screen.
