Linking cc sphere rotation to null object position.

[Carlos Dee]

in CS6 theres a new parent option jus hold control while you drag the pick whip, in this case parent the eyes to the null object and hold control, you will see on the timeline the parenting details explained, its going to be in the area where the expressions go, theres 2 different types of parenting now, hopefully this helps, if yur not using CS6 get the trial =)

You can use the lookAT Expression method.

You’ll need to apply the script to a 3D layer’s (the eye(s)) Orientation property. Here’s the script –
// Start Script
TargetLayerProperty=thisComp.layer(“Pale Blue Solid 3”).transform.position;
lookAt(transform.position,TargetLayerProperty)
//End Script

There are possibly three other things you’ll need to do –
1) offset each eye’s Anchor Point to make the eye movement more obvious
2) set y-rotation to either +- 90 to ensure that it’s not on its flat side
3) set z-rotation to +- 90 to ensure that the layer is pointed at the right direction.
