Does anyone know an expression that can convert a 1 point camera (with auto-orientation OFF) and XYZ rotational keyframes to a 2 point camera (with auto-orientation towards POI) with POI and Z-orientation keyframes, but NO rotation keyframes. That's kind of confusing.

Here's a screenshot to illustrate....

Basically I want to take "Camera 1" and through expression, make it like "Camera 2".

I talked with Dan Ebberts and he gave me this expression:

This for the POI:

C = thisComp.layer("Camera 1");
F = C.focusDistance;
position + C.toWorldVec([0,0,F])

This for Orientation:

[value[0],value[1],thisComp.layer("Camera 1").rotation%360]

It almost worked, but it gets off track... as seen in this project file (especially when you look @ the top view):

I'm trying to find a way to import an After Effects camera into Cinema 4d... and having some trouble. I think if I figure this out, it might work.

If anyone has any ideas, it would be a great help. Thanks!
