The sky dome light plug-in Ultra Dynamic Sky was used as main sky dome light source for the scene. Its highly detailed and customizable parameters enabled me to add a realistic cloudy sky to my scene. At the same time. I used the ultra dynamic sky blueprint to add a rain effect to the scene, which perfectly matched the image of a dark sky on a rainy day of the scene in my mind.

Fill light with multi-channel lighting

Under some certain circumstances, multi-channel lighting is required since we only want the main object be effected by the light. In this case, make sure the object and the light source are in the same channel so that only the object we want be illuminated.

As the images show, only the character was illuminated while the other objects were not effected.
