I need to orient a layer to the camera, that is to always make it face the camera, but my camera has no orientation value's and no target, It has been animated using rotation and position only.

Any ideas on how to write an expression to do this, or where I can get example script tutorial etc.

humm for your problem...

try this expression.....
[camera.rotate[0],camera.rotate[1]+90,camera.rotate[2]]

I'm sorry I can't open AE for now I don't know if this will work

Thanks for putting me on the right track, I thought it would have required a much more complicated approach, I couldnt get your script to work, but I nailed it like this:

myOrientationX = thisComp.layer("Camera 1").rotationX;
myOrientationY = thisComp.layer("Camera 1").rotationY;
myOrientationZ = thisComp.layer("Camera 1").rotationZ;
[myOrientationX, myOrientationY, myOrientationZ]

I actually wanted to just affect the Layers Y Orientation axis so I did this instead:

myOrientationX = 0;
myOrientationY = thisComp.layer("Camera 1").rotationY;
myOrientationZ = 0;
[myOrientationX, myOrientationY, myOrientationZ]

Out of Interest, the way you wrote the script seemed a lot less long winded than my script, is there a better way to write this?

[0, thisComp.layer("Camera 1").rotationY, 0]

That one works, and lots shorter! I think I understand the syntax now!
