Anchor points in a heavy 3d layers scene

Question

hey guys,

having a drift problem where the layers in the comp gone mad and all of them drifting , since this is a cam rotation heavy 3d scene, i think all the chaos caused from the arrangement error is ofc from my side, so how can i fix it ? do i reset all comp anchors? delete all the keys from cam rotation? what? 🙂

cheers and a good day

The camera's position controls perspective. The angle of view is determined by focal length. If you move the camera and change the focal length at the same time to maintain the size of the foreground by zooming, you get that weird Hitchcokian Vertigo effect (also called the "Jaws", "Zolly", and "Reverse Tracking" shot" used to create an unrealistic visual effect.

When you are moving a camera and the actors (your layers) at the same time, and they don't have a recognizable floor to stand on, things get looking weird quickly because there is no infinity or horizon reference. Things also get very weird without a floor if the layers (actors) move at the same time the camera is moving.

Without seeing multiple views and looking at the camera and layer paths, it's impossible to figure out where the errors are and why the perspective changes look weird.
