Re: Rotate Camera without affecting Layer Boundaries

[Paul Bertham] "...i thought practically (real world) that if i rotate a video camera in front of a person, the person itself would not rotate along with the camera..."

And how could THAT happen in the real world, pray tell?

Think about it: If you rotate a camera, EVERYTHING the camera sees rotates in the opposite direction, including people. They don't get special dispensation from the laws of physics, y'know. So a clockwise camera rotation results in everything it sees rotating in a counterclockwise direction.

What you want in AE is for your subject to always face the camera and rotate as the camera rotates. One way -- among many -- to do this is to position the subject a distance away from the camera. At the midpoint of the line between camera and subject, place a null object. Parent both subject and the camera to the null.

Now, whenever you rotate the null, the subject stays in front of the camera, and any other 3D layers in the background move.
