I am having the same problem – I am animating a character and using a null to control the position of the characters pupils so that the character can look left,right, up and down.
My comp Hierarchy is something like this:
Main Comp > Eye_LFT(Precomp that is Time re-mapped so I can animate the blinking)> Pupil_LFT (This contains the white of the eye and the pupil.)
I can move my null controller and the eyes will move as needed, but adding key frames and changing the position just doesn’t work.
I’ve been through the solutions on this thread and rearranged my layers and comps so they all have the same start and ending time (Except for some layers within the ‘Eye_LFT’ pre-comp which are only a single frame in duration, which I use for the blinking effect.
Now if I disable time re-mapping, I can animate the movement of the pupils with keyframes, but I can no longer make my character blink and vice versa.
Does anyone have any ideas or suggestions at all as to why I would still have this problem?
Many thanks
