Alright, 2 years later and I finally found out an answer to something I wanted to know for kind of a long time. You see a long while ago I noticed that the floor in City Hall in Atlas Park was reflective, but only partly. This was well before we got actual reflective glass in I17 with "Ultra Mode". Take a peek at the screenies here.

And here

Now if you look at the floor, it looks nice and shiny and glossy and it reflects the room around it. The walls, the statues of the heroes, the ceiling, the information desk etc. Except something always bothered me. My character and the NPCs in the room were not reflected. Now I can't speak to the Longbow and Super Group Registrar and the City Hall Rep, but I know my characters were
not vampires.
For the longest time it bothered me, and then I noticed it again in the Arenas on the main floors.

And Here....

Once again, the environment is reflected but none of the characters are..
I always wondered what trick was being pulled to make it seem reflective, but only for certain things. Since the reflections shift with the perspective, they aren't just painted on the floor so I knew it had to be something.
Well today I was touring city zones, playing around with No clip to sort of have fun and explore things and for a moment I was really disoriented when I flew through the arena floor and saw things upside down...

And then it hit me. Those
freaking floors aren't reflective at all, they are mildly transparent and glossy to give the illusion of reflectivity! Each of those maps has upside down rooms under the semi-transparent floor to make it look it's a reflection!


And then more for City Hall



You aren't looking at a well polished floor, you are looking into an upside down universe!
Okay so I have to admit, that was pretty clever of some one to think of to give the appearance of it being reflective. It makes sense that characters weren't reflected because you would need upside down NPCs, the player characters couldn't all be duplicated by the game, and if the animations ever got out of sync itd be kind of messed up looking. Even still, pretty damned cool that I finally got to figure out what the hell was going on there.
Sorry if I'm slow to the party and other people knew this a long time ago, even still the screenies are kind of cool.
