It seems it’s not just a checkbox issue.
If I make a new solid on the inner comp and link its opacity, say, to a layer in the outer comp, when I close out the pick whipped expression, AE tells me there is no such layer named for the one I just picked and disables the new expression.
I could begrudgingly accept this if all the other expressions that are currently running in the inner comp using data accessed from the outer weren’t working, and the entire cross comp expression routine was failing, but the Checkbox test and this new routine are the only ones that fail – all others, and there are a lot of them, are working fine.
Have I hit a high water mark?
Cheers,
