How to animated a 3D object?

I'm wanting to create a short promotional video for my wedding business, and i want to show off the Blu-ray case and disc that they'll get at the end, but I want to do it in a 3D environment with the case floating in and rotating.

I did this years ago for DVD's by simply making a 3D environment and adding the front, back, and spine .png files into Motion in a group, and then rotating them and moving them in 3D space to make it look like a box shape.

Are there any plugins or ways to use Motion now that I'd be able to possibly download a 3D Blu-ray case somewhere and animate it in 3D space in Motion?

Here's a sample of what I did years ago. It's at the very end of the video at 3:50

1 - Get mO2 from MotionVFX
www.motionvfx.com/store,mo2,p2345.html
2 - Join the mO2 Users group on Facebook
3 - Get some free DVD models and DVD casing models from various sources the folks on the FB group can steer you to.

mO2 is pretty easy to pick up the basics of, and if you get addicted, you can go very deep, but you don't have to, in order to produce some really wicked cool stuff.

In fact, you could easily create a DVD disc and case out of "Primitives" in mO2 that with the correct texturing, you'd have amazing results from.
