Adobe After Effects 3D Layers and Camera Tools

Question 1

How do you convert a 2D layer into a 3D layer in After Effects?

Accepted Answer

Enable the 3D Layer switch (cube icon) in the Timeline panel

Answer

Clicking the 3D Layer switch gives the layer Z-position, X/Y/Z rotation, and material options for 3D compositing.

Question 2

What is the difference between an 'Active Camera' view and a custom camera view in After Effects?

Accepted Answer

Active Camera shows the final render view through the lowest-numbered camera; custom views are for navigation only

Answer

Active Camera renders from the enabled Camera layer's perspective; custom views (Front, Top, Right, Custom) are orthographic navigation views that do not render.

Question 3

What does the 'Point of Interest' property on an After Effects camera do?

Accepted Answer

Defines the 3D point in space that the camera continuously aims at

Answer

Point of Interest keeps the camera always oriented toward a specific XYZ coordinate, even as the camera position moves.

Question 4

What is a 'Light Layer' in After Effects used for?

Accepted Answer

Illuminating 3D layers in the composition using simulated light sources

Answer

Light Layers cast illumination on 3D layers, with types including Parallel, Spot, Point, and Ambient for different lighting scenarios.

Question 5

What is the 'Auto-Orient' option 'Orient Along Path' used for on a 3D camera or layer?

Accepted Answer

Automatically rotates the layer or camera to face along its direction of motion

Answer

Orient Along Path rotates the camera or layer so it always points in the direction it is traveling along its motion path.
