CMG Hidden Gems: Chapter 13 - 3D Space covers the basics of working with 3D layers in After Effects and includes moving, rotating and animating layers in 3D space, offsetting their anchor point in Z, as well as auto-orientating layers along a 3D path. Also covered is using the Composition’s 3D Views, View Layouts, and Axis Modes, along with the rendering order when mixing 2D and 3D layers.
CMG Hidden Gems: Chapter 14 - Camera covers creating and animating a camera, including creating camera rigs and taking advantage of auto orientation, as well as showing how to cut between multiple cameras.
