I’d also like to add that despite disabling layer cache, when I make a change to the null object keyframes the render bar remains green and the whole thing hangs on to the old keyframes that dont exist anymore.

So I decided to parent the camera to a null and use its Z rotation for the camera. I first tested this out with a seperate AE file using only a square and it worked just fine. However When I do this in my normal comp, the behaviour remains the same. You can see my keyframes here:
and as you can see despite the Z being at a different value, the null object is still just acting stupid and staring right at me:
How is it that this behavior affects even the null object? could this be a problem with particular? Also, I have disabled layer cache and that has not had any effect.

I would love to update but unfortunately the schools IT department control all of that. I am unable to re install or update until they decide to answer my calls :/ Freelance sounds better every day! lol
Mr. Dave, would I parent the objects to the null and spin the null? or parent the camera’s focal point to it instead?

would I add that to the end of the y=” ” line? where does the number 262.4 come from?

Bravo! It is close to working now! The issue I have at the present is that because the layers are following the y position (and they were drawn with perspective) they all have the exact same y value. This is a problem because each of them need to have their own y value. My thought was to find the difference between each of their pre-expression y-value and subtract it from the nulls y value. However, this does not seem to be working. I think because of the syntax, each layer is extracting the value of the layer before it and then subtracting I will demonstrate this with a screen shot below. So where in the current expression do I need to subtract the y value?

the topmost expression shows me adding to the y-value. This is because the difference between this layers original y-position (744.4) and the null (482) produced a negative value, and we all know that two negatives make a positive! right?

thanks for the reply! I’m away from my mac pro and don’t have the pain threshold to test it out on my 2007 macbook pro. So I will test it out at work tomorrow! I can see what’s going on here but if you have a chance could you explain this? from what I can see, you are assigning the de-sync expression to “y.”but how is that last bit work?

Try key framing the vertical orientation and (using keyframe assistant) toggle hold keyframes. You can then tweak the speed to make it more realistic with the graph viewer
