Text following null object....animated object

Hi all,

I’m working on a project where a 3D animated book (opening slightly, with a light camera move) is rendered in Blender and imported into After Effects as a .mov file.

I’ve used AE’s 3D Camera Tracker to create a null that follows the book cover quite well. I then parent a precomp text layer to that null. However, once the book begins to open, the text drifts or detaches slightly from the cover.

I’ve tried:

Parenting a precomp to the null

Using Mocha AE for tracking

Corner pin + Mesh Warp
But I haven’t found a stable solution. I want the text to appear as if it’s printed on the cover – moving along with the perspective of the book throughout the animation.

Important constraints:

The solution must stay within After Effects.

No external plugins (like Mocha Pro).

Text should remain editable in the comp.

Question:
What’s the most reliable method to attach editable text to a moving book cover, based on a tracked null, without using plugins?

Thanks in advance for your input.
