exporting null data to AE

I've tracked my scene, created some geometry and animated a object (airplane) moving in and out of the geometry. I'd like to composite some greenscreen footage of my head following along with the airplane in after effects. How do I export the (airplane) animation data as a null to after effects so that I can simply attach my greenscreen asset to the null and be done?

Thanks in advance

If you only need the transforms with no animation on, just create a locator and bake it as an .ma file. Remmeber to do the same with your camera. Edit > keys > bake simulation.

If you need the locator to move along an object, you can parent constrain the locator to your geometry.

My last information was, that your locators have to be named NULL1, NULL2, ...

Yes this is true. Sorry I completely forgot about that. They have to be named null<something>, for AE to be able to read them as Null objects.

Heres a small test scene with an animated camera and cube and 4 locators.
They have all been baked. The constraints on the locators can be deleted, I just left them there so you can see how they work.
When you import it into AE, remember that the NULL objects have an opacity of 0%. You should also scale them down a bit since they are enormous.
