Replacing a 3D element with another

Instead of repeating all the steps to position the back cover, you’ll duplicate the front cover and replace it with the back cover.

1 Select the AEFront.jpg layer in the Timeline panel, and press Ctrl+D (Windows) or Command+D (Mac OS) to duplicate the layer.

2 With the duplicate layer selected, press P to display its Position property.

3 Change the z-axis value to +56 to move the layer away from the active camera view. Because this will be the back cover, you want to position it at the back of the spine, which is 112 pixels wide.

4 In the Composition panel, change the right view to Custom View 3 so you can see both ends of the book.

5 With the duplicate layer selected in the Timeline panel, press R to display the layer’s Rotation properties, and change its Y Rotation value to 180 degrees. The rotation flips the layer.

6 With the duplicate layer selected in the Timeline panel, press Alt (Windows) or Option (Mac OS) as you drag the AEBack.jpg item from the Project panel onto the duplicate layer. After Effects replaces the front cover with the back cover, and changes the layer name to AEBack.jpg.
