Do you have gravity on in Shatter? Are you at the beginning of the comp? It sounds like it's already shattered and fallen so that's why you're not seeing anything. If that's not it, we're gonna need some more info on your project (with some screenshots, perhaps) to be able to offer better hep.
The OP simply doesn't understand how Shatter works and that it can't be combined with other animation stuff in most cases. That's all there is to it. No magic or endless excchnage of screenshots required. The custom shatter shape is determined based on the first frame and can't change over time, which is exactly what happens here...
Oh, I see what he's trying to do now. Yeah, you're right. OP, that's not going to work. If you want to do stuff like that, look into Zaxwerks 3d Invigorator or Video Copilot's Element.
