Correct…and all layers are at 0 on z axis, except for the trapcode z axis which is greyed out (as it performs in its own 3D space on a 2D layer).
The only other workaround is to disable the camera (cancels the 3rd axix), but then the image on the layer i am trying to copy is is mostly off the screen. I then need to center it and then make the “saved frame”. Again a number of manual adjustments that then need to be undone.
I guess I thought there might be something more obvious that I was overlooking?
