Tracked text problem

Hey everyone,

 

I am pretty new to AE but not a complete beginner. I've been searching for 2 days (no joke) but without any solution…

 

I have a short video where I tracked a 3D text in it. As you can see (see attachements) my camera angle is moving from down to top and the text is perfectly tracked where it shell be. 

 

Now the problem is that the text is rotating / tilting while the camera is moving from down to top. But the only thing I want is that the text just stands there without any movement or rotation. As a fixed text with my perspective stuff on it. 

 

I've tried it with track motion and a Null-Object and in another version with the Camera 3D-Tracker. 

With the Null-Object: the text is perfectly where it should be but it is rotating the more the video continues. (see attached files 1-2 [null1.png and null2.png].

With the Camer 3D-Tracker: the text is also perfectly where it should be but the angles are tilting. So it doesn't stand straight the more the video continues. (see attached files 3-4 [3d_camera1.png and 3d_camera2.png].

 

Hopefully you can help me.

Kind regards

Use the toComp Expression Method to link a 2D copy of the Text Layer to its 3D Layer copy.
1) Create a 2D Text Layer with the same text as the 3D Text Layer

2) Paste this Expression into the 2D Text Layer's position property –

targetLayer = thisComp.layer("3DTextLayer");
targetLayer.toComp([0,0,0])

Well, mucking around with Orientation (Ausrichtung) is fundamentally evil. It's the old Quarternion vs. Euler rotation thing and how it affects calculation order in 3D psace. Start by disabling and resetting these properties and only use the separate rotation values only to get your camera and text aligned properly.
