That was informative, Walter. Thanks.
Still, I'm curious as to how it works in terms of compatibility. Is a project file containing a layer utilizing a Pseudo Effect universally transferable without requiring installation of additional components? In other words, would that Pseudo Effect instance show as missing on a different machine?
You see, my arrival at this thread was catalyzed by an Ae file with a piece of animation generated using Animation Composer (I assume you've heard of it). Interestingly, despite me not having the generator plugin/extension itself installed on my unit, the Pseudo Effect expression control group still shows. I had no idea you could do that. My understanding was that you were limited to just stacking the built-in expression controls from the menu.
