In Brick Rigs, an Unreal Engine game I've been playing a lot recently, while designing your vehicle, you are able to toggle its lights and see how they look without driving it.
In Unreal 4 Automation's car designer, will you be able to do this? Or, in photo mode? For example, you could have a scene in the photo mode, make it night-time, then turn the car's lights on for some visibility or to give a sense of attitude to the photo. Or, you could toggle some lighting in the car designer to darken the scene, then turn on the car's lights to see how they look.
I assume that you could find the middle of a headlight fixture and place a spotlight facing infront of the car. Taillights and indicators could just be area lights.
I'm not a game developer, so is this too hard to achieve this?
