What is the best way to moving objects and fade objects while rendering matinee video?

Hi guys! I want to know what is the best way to move objects and fade objects while rendering matinee video, because i need open a building’s garage door and fade some structural columns when the matinee camera walk along the trajectory inside the building using blueprints.

At first I was thinking of using the matinee camera as an actor to collide with a trigger that activates these animations, but I can not. Like the UE4Arch videos. without direct player interaction, just movie.

And taking advantage of the topic i wonder if this affects the light in render.
