Pointing to an object in a 3D precomp
Hi,
I’m not sure it can be done and I hope I ‘m clear about what I’m trying to do.Basically, when I distribute objects in 3D space, in order to point the camera to a specific object I do like this:
– link the camera to a 3D null
– copy the position of the target layer
– paste it to the position of the 3D nullNow the camera is pointing at my target object…
Can I do the same thing if these object are inside a precomp with collapse transformation on?
I have a pre comp with my objects distributed in 3D space and I need to use different instances of this precomp but I would like my camera to point exactly at a some layers inside this precomp…
I know I can do this by hand but I was looking for a more precise method… If it even exists…

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.)

Yes. That is what I was trying to do…
Many thanks…
