3D Null into 2D coordinates
Hey Guys,
I am looking to use the data of a 3D null that was exported from a 3D app. And use that data on a 2d coordinate for something like a lens flare.
So I have all my imported nulls and an AE comp setup. I just need to somehow parent the imported 3d null data xyz onto a 2d xy effect.
Make since?How would you go about doing this?

Position properties like this are stored in an array formatted as position[0], position[1] and position[2]. You can apply a basic expression to your 2D effect’s X and Y properties to link them to the null’s X and Y values. The nice thing is that it’s much easier than it sounds.
On the timeline Alt+click the stopwatch icon for the X value of your 2D effect, then enter the following expression:
thisComp.layer(“Null 1”).position[0]
For the Y value of the 2D effect, use this expression:
thisComp.layer(“Null 1”).position[1]
The above expressions assume your null is named “Null 1” so change that wording accordingly.

yup, that’s the ticket. Thank you.
Wish pickwip was smarter so I can be dumber.
Cheers
