I am working on a project where we will be putting green screens on all 4 walls of a room. I need to be able to put "fake walls" on each of the 4 walls in post and track them as I move the camera around. Can anyone point me to a manual for how to do this with AE. Thanks in advance!
AE has no way of calibrating the tracker and stitching multiple trackers together in a way that would result in a consistent 3D scene. Even attempting this in Ae would be a nightmare. Sorry, but you need to move on to greener pastures and use advanced compositing tools like Nuke or dedicated tracking tools like SynthEyes.
