Thank You, Dan!

I got the idea: let each layer refer to the master layer, rather than to a neighbor.
Now it works fine.

My expression for Y rotation is:
thisComp.layer(“c1 master”).rotationY.valueAtTime(time-(thisComp.numLayers – index + 1)/25)

Same for X rotation.

And the shape layer size expression is
k = (thisComp.numLayers – thisLayer.index+1)*20;
[k, k];

Inititally there are two layers: “c1 master” with keyframes, and the “c2” with these exp. Then just duplicate the “c2” 20-30 times to get extra circles.

Let me credit Satya Meka at ae.tutsplus and Mark Coleran for the concept of the effect.

Kind regards,
Sergei
