Nothing there but 3D layers lights and cameras. Motion is key framed. It's not a plug in, it is just basic animation skills with possibly an expression for the bounce.
Thank you very much for a quick response, Rick.
Yes, for sure it was a 3D layer, but accomplishing those smooth bounce movement and then stacking each photo is the hard part.
I actually tried to do the same with Trapcode Particular with no success.
Could you guide me somehow to the expression it is using for the bouncing part?
You could look up the Ease&Whizz script, but it's really just some simple rotation keyframes....
Thanks Mylenium, but I don't think Ease&Whizz script can do this effect. I will try doing this effect through keyframes as you suggested. Thanks again.
