Hi, I remember that someone said this is possible ... today was the first time I've tried it and the pickers rubber band slashed back (nearly on my nose) when I pulled it tfrom one timeline layer to the other timline layer ... it didn't want to accept parenting of layers in different comps.
I found that I can tie position or rotation etc. by expression like this for example :
but this is not parenting in terms of distributing from the center of the parent ... or am I wrong ?
You are referencing a property, not parenting. It merely copies values from one data stream to another ratehr than doing full transform calculations.
ah ok, and is there a possibility to create parenting between layers in different comps ?
Nope, not really.
You could tie your anchor points together via expressions too, or add offsets in the expression itself.
