Wow, thanks for the effort! I’ve been away for the holidays so sorry for a late response.
Though the project I was working on is over now and I just slogged through changing all the layer references in the expressions to get it done, any help in a script would be very useful to me and, I would imagine, others as well.
Transform properties only would certainly be useful in the future and could be a starting point for you and other great minds to create a script that could streamline this process.
Just a thought prefaced by the fact that I know nothing about writing scripts, but is it possible to direct a script to just look at a comp’s layers for any expressions regardless of whether or not it lives in a transform property or an effect?
Thank You
