First off I do want to say that I absolutely love the graphics and direction that these ∆ games are going in. But there's just one thing that always bothers me about this and many other UE5 games. For the lights you have an emissive material because you need it to glow, but it has the side effect of making these light splotches everywhere. You can go into the emissive material settings and somewhere in there there's the option to have it emit light. If you uncheck that the game would look so much cleaner and you will still have the glowing effect.
