Change Fog From Blueprint?

Hey there. I want to trigger a sequence which changes exponential fog when clicked a button . But i cannot cast level blueprint from my widget . And also i cannot change my exponential fog from any other blueprint except level blueprint because i cannot get exponential fog reference from my ThirdPersonCharacter BP . Even casting to exponential fog (and fog component as well ) give object wildcard errors which makes it impossible to use exponential fog from Blueprint . I am just starting out with sequences , please help out .
