No, they don't sparkle.
From the campaign:
The Vampire's Codex is a tabletop RPG set in a modern Gothic Noir world. You can play as a Fledgling Vampire, a Mortal Acolyte, or a Fiend Hunter as you uncover the shrouded history of the cabal that conquered the conquerors...
The Setting style can be best described as Underworld unravels The Da Vinci Code in cynical tone of The Maltese Falcon.
