I run CS3 so the only solution I’ve heard so far is to animate it in C4D which puts as a 2D layer in AE. I barely understand how to use C4D so I gave up on it for now. You can use the shatter effect in AE but it has a few flaws but its a simple solution. Theres a tut on here how to do it.
I’ve heard rumors that you can do it with C4D if you run CS4. I don’t know if thats true or how to do it. Boris has a plug in that does it if you have an intel mac.
Wish I could be more help. I heard the new CS5 will have a plug in that does it but thats a month way, expensive, and you need an intel mac.
