Is there a ready-made script to search/edit a certain parameter in multiple effects across layers and comp. I searched aescripts.com, but can't find any. There are scripts to search expression, or effect names. But not specific effect's parameter. Using AE's native search function, you can't get a specific effects parameter if it shares the same name within other effects that you don't want to edit. For instance, I want to search/edit "path" parameters only inside 3D stroke effect on multiple layers without showing other path parameters.
Beside, for beginners in scripting. I wonder if it's difficult to learn to write a script doing this task.
