Hi!
Try applying this little expression to the position-parameter:
d=0.5;// This is the offset-time in seconds
thisComp.layer(2).position.valueAtTime(time-d)
And this to the opacity:
d=2;// This is the offset-time in seconds
thisComp.layer(2).opacity.valueAtTime(time-d)
These expressions assume that you have at least two layers in your comp. The “master” layer is the second layer (#2). This is the one you keyframe. If you need to change the reference just edit the “2” in “thisComp.layer(2)….” to the index of your choice.
Hope this helps!
Good luck!
Cheers!
