Here is the updated version of the open world dynamic weather raining system I worked on previously in open world series. I have updated the system to work with unreal engine 4.25 here. You can download it using the link above. as the rain starts, rain particles and sounds will also be activated and the wetness of the world will be gradually increased. After rain is stopped, world will be dried in some time. Also the water droplets and leaks will start to appear on the screen or the surface of player camera.
