Well, not completely the case, there is a pick whip on each of the layers, however, there isn't one where I need it. i.e. I'm trying to attach the motion tracking attach point, to an effect on a different layer. or on the same layer as in this pic example.
Am I missing something?
Alt+click the stopwatch and an expression pickwhip will appear.
man, you are my hero. Thanks for that, it's been driving me insane!
