I adjusted some of the lights in Unity, and I added illumination effects for the windows and candles. I also added subtle light beams coming from the windows and projections of the window lights on the floor, plus some dust particles for a bit more motion.
I was conflicted on how dark the scene should be. It doesn't really affect the visibility of the of the Whitemane model because she uses mostly flat shaders, but for now I erred on the side of the scene itself being a little brighter, because a bright Whitemane model in a super dark room might look weird. I might adjust it more over time.
I added the background scene to the testing page. You can't really look around the scene yet, but I included mainly to get your feedback on if the lighting and particles affects the game performance in any way.
Up next, I'll be making a system to handle Whitemane's animations. I'm going to start simple by adding her idle throne pose first.
