I notice the lighting changes among the stages, I just wouldn’t label it, a glitch. I think they are trying to do what a lot of lighting effects do, and that is adjust character’s lighting, depending on the atmosphere. Look at the second Sabrewulf pic. It’s different than the first pic, cause he’s next to a light. The Agonos stage, is more of a bright sunny setting, opposed to the more gloomy look of the Thunder stage. It seems like they are trying to showcase that on to the characters. It could t be, they just don’t have the talent or skills, to do that successfully, or need a new engine.
