So I am working on a short for my Advance Visual effects class. To sum of up the short a man runs into a bathroom freaking out...looks towards the mirror, interacts with the faucet, and takes out a pill capsule and swallows a pill. When the man takes the pill he starts grasping his stomach in pain and raises back up to a arm that has burst out of his stomach...the arm then begins to count down from three.
I know how Im going to shoot everything up to the arm bursting part. Since the man will be out of shot during the burst I dont need to worry about creating the burst effect, but I will need to be able to create an alien looking arm and track it. Im just curious what would be the best way to do this. Iv thought of using two shirts one without track points and one with and tracking a 3D model onto the shirt. My also thought was taking an arm prop and applying it to the shirt and changing the way it looks in post.
