Master the 3D Camera Tracker + Object Matte in After Effects

I took a flat graffiti wall and a handheld shot and made the whole thing come alive in After Effects — projected abstract stock footage onto the wall and the doorway with the 3D Camera Tracker, kept my subject in front of it with the Object Matte tool, then blended the edges with a light wrap so it actually sits in the shot.

No Mocha, no planar tracking. Just the 3D Camera Tracker, some nulls, and a bit of roto.
