Hello, I am attempting to prototype a sort of architectural setup that will allow someone to import a scene into Unreal, hit play, and toggle the scene between night and day at the push of a button. While I understand how to do most of this, I am attempting to account for emissive materials on things like windows or streetlights and have hit a roadblock. I cannot figure out how to affect these materials in the blueprint without already having the objects they are attached in the scene. Is it possible to use some variant of the Get All Actors nodes to target this, or how else might I go about it? Is it even possible to do in the first place?
