It’s not good for big scenes quickly, and that’s a well established fact. Sure, you can have massive scenes in Blender, but viewport navigation/rendering/shader compilation are all going to be very slow. No DCC is going to handle large scenes as quickly as a game engine. Just load up the UE5 demo or the Moana island data in Blender and try doing some viewport navigation or rendering and you’ll see why Blender isn’t sustainable for massive scale scenes
