Problem with the light of the character

Hi Everyone! My name it’s Alex and I have a little big problem with my project, I’m new with Unreal, and I’m doing a game scene like Silent Hill or a survival horror of the ps2, and i tried to do a dark scene without lights of the enviroment. And I was setting differents spot lights, and well my problem it’s that my character and the third character of Unreal have no light when i put the intensity of the Light Source to 0. Please, can you help me? I want to see my characters but i don’t want to see te bright of the Light Source in the enviroment. Thanks
