Hello, I just got the Steam audio plugin to work with fmod and my UE5 project, and there is a big noticeable difference in the audio sim (Very cool). My problem/confusion is with how the Steam Audio Spatializer looks in fmod compared to the Steam Audio Documentation.

My Project:

Steam Audio documentation:

Is the documentation not up to date or is the plugin not correctly integrated into Fmod?  
Fmod version - 2,03,12  
Steam Audio version - 4,8,1

An FMOD Studio plug-in typically consists of two files:

- **A .dll file,** which contains the actual workings of the plug-in: How it processes sound, what variables it has, what inputs it takes, and so on.
- **A .plugin.js file,** which defines how the plug-in is presented in FMOD Studio: How controls are labelled, what order they’re presented in, how they’re grouped, whether enumerated properties should be presented as dials, number boxes, or drop-down menus, and so on.

Judging by your screenshots, something is wrong with that second file; perhaps it’s missing, or has the wrong name, or has been put in a different location to the .dll, or something similar. Whatever’s wrong with it, FMOD Studio is unable to detect it, and so is falling back on its default method of presenting a plug-in’s controls: It’s ordering them by type only, displaying nearly everything as a dial, and not presenting any custom graphical displays.

Looking at the Steam Audio documentation, the file you need is called `src/phonon_fmod.plugin.js`, and you should be able to find it in `steamaudio_fmod.zip`. Is this file missing from the .zip? If it is, you will have to obtain a copy of it from the developers of the plug-in.

You are right I found the .js file and placed it in the same location as the .dll files
