2d tracking problem
Hi
I’m having an issue with 2d tracking. My null object stays in exactly the same place in the video, as it should, which indicates the tracking works pretty well. But the text that I attach to it (which has the null object as its parent) moves independently. I can’t understand why it doesn’t follow the exact same movement as the null object since it’s attached to it and should move relative to it.
Any suggestions?

Is the text 2D as well?

I tried it with both some pixel-based graphics as well as text layers made in AE.

Check the anchor point of your text layer. Also make sure that you haven’t turned on the 3d switch in any of the layers.

Hi
The problem is that if I don’t turn on 3d on the text layer I cant light it.

If your text layer is 3D, you either need to use 3D camera tracking (if the footage has a camera that actually moves around in 3D space) or you need to render a still image of the text with alpha channel and import it back into AE as a 2D image and then attach it to a null. Or you can precompose it together with the camera and the lights so it essentially becomes a 2D layer, and attach that precomp layer to your null.

Thanks, I’ll give it a go and see how it works!
