hey man! in order to solve this 100%, i just need to know:
is the tracking null itself parented to anything, or does it have Scale/Rotation values in addition to Position?
If you tell me how you created/applied the track (e.g. Mocha, AE 3D Camera Tracker, point tracker, position track) and whether the null has Position only or Position + Scale/Rotation.
Lemme know, don’t panic, i’ll give you the solution after your response.
Or if you can, send me the projet file, and i’ll send it back fixed for you in a minute. thx!
