Try turning off auto orient and use this for orientation:

 

v = thisComp.layer("Camera 1").toWorldVec([0,0,1]);

lookAt(position,position+v)

Probably so, I just need to find that math! :-)

I need to keep some 3D layers flat in screen space. One immediately reaches for the Auto Orient switch. It seems to get weird on the screen edges as a layer approaches the camera. I tried Dan Ebberts go to expression for Y only orientation(http://motionscript.com/design-guide/auto-orient-y-only.html) but that doesn't do the trick either. I bascially want the layers to be rotated so they have no perspective but still stick to the 3D position. 

 

I'm sure this has been done before...
