Re: Pointing to an object in a 3D precomp by Cassius Marques on Mar 26, 2015 at 1:16:31 pm
I'm assuming you want to get the current position of a layer to keyframe a camera animation. The simplest way would be to keyframe and animate your camera inside this precomp, then copy/paste the camera to the parent comp and compensate its transformations for any space/time discrepancies.
You can also use expressions that access and translate any space coordinates of any layer inside any comp to any other comp. (e.g creating a null and "linking it" to the layer you need to address, so you can copy/paste as you're used to.)
