Thanks for the reply, BrickTop, I’ll definitely try out some of your suggestions.
Using “ambient lights” helps in some areas, but in others it’s impossible to place them without also illuminating areas that should be dark. Taking my screenshot above as an example, I see no way of placing ambient lights to brighten up the shadows outside the cube without also hitting the inside. But maybe that’s just a limitation of the engine after all.
Thanks for sharing your approach in any case. It would indeed be nice if others could chime in with their experience as well.
