oh i see, no ive already shot the footage and planned to do this in post production if possible? are there any tutorials on rotoscoping as im not sure what it is! for that matter ive no idea what caustics or placements are. as i said im new to AE, sorry!
lets just say I have a part of my film where the character walks up to a mirror only to reveal he cannot see himself, he then touches the mirror and still no reflection. How do i get the character not to reflect in the mirror from when he wlaks in the room all the way up to when he leaves (after touching the mirror)
