This is the part 18 of #Unreal Engine Open world game development #tutorial series.
This episode focus on implementing a dynamic rain system, which is a part of dynamic weather system of the game. Here, we will extend the global wetness controller we implemented in previous episode to be controlled by a blueprint and 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.
