I just got my Occlusion working for a single sound. In Fmod I have a local param “Occlusion“ that’s doing the effect change, and in UE5 I have the occlusion enabled for the Fmod component, and that works on its own in UE. Now I want to scale it for almost ALL my sounds. How can I do this besides ctrl+c and ctrl+v the effect onto every event? I haven’t had luck with snapshots because they don’t seem to take every sound’s individual occlusion value, and looking at this old post the only way would be to group select the events and edit them that way.

There are different ways to go about this, depending on what suits your needs best. But for something like Occlusion I would suggest setting up a [Shared Effect](https://www.fmod.com/docs/2.03/studio/glossary.html#shared-effect) which you can add to any events that you want to be affected by Occlusion.

Is it the Preset Effect?

Yes that’s it, in FMOD 2.02 it was called “Preset Effects” and it was changed in FMOD 2.03 to [“Shared Effects”](https://www.fmod.com/docs/2.03/studio/welcome-to-fmod-studio-new-in-203.html#terminology-improvements).
