Better Lighting

Transform all the lights on the map into 3D lights with effects and HD included that will make your game a much more visual and realistic experience, giving you very good visual effects. Adjusting all the lights on the map and checking that there are no bugs. Shadows have also been improved and you can adjust shadows in the L4D2 settings menu just like lighting. And finally it will add RayTracing to the illuminated parts but it will not be very exaggerated.
