comp camera rotation with Shatter – HELP!
I realize there are many posts related to the shatter 3d “hack” but I’ve yet to find a solution.
I’ve used shatter to extrude a shape I’ve created (i’ve constructed a 3d television using flat shapes and am workin on the antenna). Anyway, when rotating my comp camera around my shattered object, the object does not maintain it’s position in 3d space relative to the other objects in the scene…does that make sense? I need the shattered object to maintain it’s position in 3d space as I move around with my camera, but it seems to have a mind of its own. I’m using the comp camera in the shatter settings, my shape layer/shatter layer is in 2d, I’ve adjusted my depth and gravity to restrict any actual shattering…No Dice. HELP!

Hmm … it sounds like a parallax thing. (I’ll give it parallax more shot) I could be wrong, but I think that you should move the rest of the objects (3D layers?) so they match up with the shattered object. Maybe the Shatter force sent the object slightly forward, where you didn’t expect it to be?
Try adding a new solid, with Shatter at the default (but using comp camera) settings — then you might see how things line up when you compare them to the unshattered portion of the default wall.

yeah, i’ve tried just starting from scratch with a simple cylinder shape, no good.
The shifting that’s happening is definitely the appearance of parallax – but i don’t know how parallax relates to working in after effects. the shatter object is shifting disproportionately to my other 3D objects. That is, i put the object in front of my 3D cube, rotate the camera around to the back, and the shatter object has rotated around for the ride – it’s now in BACK of the television. I want it to stay still, dang nabbit.
I realize I’m trying to make AE into something it’s not, but it’d still be nice to find a solution for my own education. Next time I’ll stick to Cinema 4d!

Oh … I see. Shatter objects don’t respect other 3D layers, since it’s a 2D layer that just uses the Comp camera position/rotation to control how it looks to camera. It doesn’t know the other (3D) layers exist. You’ll have to split the Shatter layer and slide it above or below the other layers in the timeline when appropriate.
AE has its limitations, and they’re almost all in the 3D realm.
