Read more details here. Also, an Italian source shares that Rob's Abs are rock-solid real:
"These are markers to help the person who is creating the effect put the diamonds on his body later and it will be composited,² Elephano, production supervisor in the animation department at USC's School of Cinematic Arts, tells us."When he moves the diamonds stay with him in 3-D space, farther and closer, the shape of the diamond will change depending on how far or close he is when he moves from the camera.
Not that it matters if Rob is sporting a faux-pack; I don't care if he has a six-pack...We love him regardless, right ladies? :-)
Our on-set source says that, despite the special affects abound in the vampire flick, the toned up bod belongs to RPattz and not a computer screen.
"He looks absolutely amazing, and the six-pack is real, so, so very real!" the source says.
Thanks, Loan & Alexis!
