I'm not sure if a 3D gallery would be needed since I've always just used cas to look at the characters outfits etc but who knows.
What's there to look at anyway? Low polygon models of characters and weapons that reuse assets from ten years ago? :/
I really hope the faces/bodies are just placeholders... But we are talking about Namco here, they did the exact same thing with Tekken 7. The big "graphics overhaul" of Fated Retribution was just slapping tons of ugly image post processing effects like film grain, chromatic aberration and color filters on the game.
