Yeah, I agree. Material shaders on the characters' clothes and equipment are also fantastic, and so are animations of course. And effects/particle systems.I was really pleasantly surprised at the quality of their post processing AA (especially for japanese games that usually don't usually stand out here) that manage to eliminate most of the obvious shimmering, as well as the middleware GI solution.
Again, for a middle-class budget game, this is not supposed to be a priority at all, but the fact that they still tried is great. While it is not perfect and fully dynamic (which games featured such a thing anyway in the first place ?), it manages to ground and blend the characters and the environments together quite well. The characters, especially their skin when properly lit, look really good.
I managed to talk to Kaldaien, and I'll provide him with the code to integrate. (Working on it right now)
