Accessing position from parented item for use in expressions
Hello:
Yet another expression question. I’ve parented a 3D camera to a null (to faciliate arcing around layers arrayed in 3D space) and I’ve parented that null to another (to facilitate moving those parented items in xyz space). That seems convoluted, but it seems to work the best for what I’m trying to do.
I want to apply the camera’s x position to a fractal tunnel effect position so that when the camera moves to the left the vanishing point of the tunnel will move too. I had a working expression for this, but when I decided to set up this parented relationship that expression stopped working because the camera now has no independent positional keyframes (its x position stays at 0).
So is there a way to send the camera’s global positional values to that expression? Or is there an alternative way to do this?
Thank you.

This should give you the position of the camera in world space:
C = thisComp.layer(“Camera 1”);
P = C.toWorld([0,0,0]);DAn
