Rotation of layers with CC Sphere
on Aug 11, 2009 at 4:08:43 pm

Hi all,

I saw this clip:

http://www.vimeo.com/5506977

I read somewhere what the clip was done entirely in after effects. Is there a way to link 3d layers to the rotation of a globe created with CC Sphere? so that they rotate together? Any tips?

seems like the layers are not sitting on the sphere..they are sliding a little..

maybe the layers parented to a null and rotated on it's own at the same speed of the sphere??

hmm....

Here's what I've got so far.

I've managed to link up the rotations right but by parenting the camera to a null with the expression:

lookAt(thisComp.activeCamera.position,postion)[0]

on my CC Sphere layer's rotation properties does not seem to work. It only responds to when the camera's position/poi is adjusted. Can anyone help? here's the file so far:

Ugh. I Iooked at that clip, and if it really was made in AE, the person who did it had troubles galore getting it right. Even though 3D applications are tough to use, it would still be easier to pull this effect off using one.

If you've got the layers parented to a null, I bet the rotation of the null is wrong. But there are other hurdles to overcome, too.

What? Apparently you're unaware that the CC Sphere effect does NOT make a 3D object, it makes a 2D image that merely looks like a 3D object.

Just one more reason for using a 3D application.
