As can be seen in many first-person shooters and survival horror games, lights and shadows can add a great deal of realism to a Scene, helping to create the right atmosphere for the game immensely. In this recipe, we will create a cloudy outdoor environment using cookie Textures. Cookie Textures work as masks for lights. It functions by adjusting the intensity of the light projection to the cookie texture's alpha channel. This allows for a silhouette effect (just think of the bat signal) or, as in this particular case, subtle variations that give a filtered quality to the lighting.
