Motion newbie here, so apologies if this is an easy one, but I can't find it in the manual or previous posts:
Is there a way to extrude or otherwise add a little 3D depth to flat objects? I'm dollying a camera forward, past several layers of image (layers created in Photoshop), and I'd like to see just a few pixels of Z-axis thickness on those objects as the camera moves past them.
The images are irregular shapes, so simply building a cube behind them won't quite do it.
You can make replicators of the objects and have them replicate only along the object's Z-axis, creating the appearance of an extrusion. Peter Wiggins shows an example of doing this with text in this tutorial.
