hello,  
I followed the karting integration tutorial and everything is working well, but when i add my custom granulator plugin to any events in FMOD, it breaks and gives me this series of errors:

[FMOD] PluginEffectModel::init : Missing DSP plugin ‘NTGrains’

UnityEngine.Debug:LogWarning (object)  
FMODUnity.RuntimeUtils:DebugLogWarning (string) (at Assets/Plugins/FMOD/src/RuntimeUtils.cs:578)  
FMODUnity.RuntimeManager:DEBUG\_CALLBACK (FMOD.DEBUG\_FLAGS,intptr,int,intptr,intptr) (at Assets/Plugins/FMOD/src/RuntimeManager.cs:108)

and:  
[FMOD] PostLoad::initPluginEffects : DSP plugin returned an error, bank will not load properly.

UnityEngine.Debug:LogError (object)  
FMODUnity.RuntimeUtils:DebugLogError (string) (at Assets/Plugins/FMOD/src/RuntimeUtils.cs:594)  
FMODUnity.RuntimeManager:DEBUG\_CALLBACK (FMOD.DEBUG\_FLAGS,intptr,int,intptr,intptr) (at Assets/Plugins/FMOD/src/RuntimeManager.cs:104)

I placed the dll file in in the assets/plugins/FMOD folder, but still breaks.

any help would be great ! :3

Hi,

Thank you for sharing the information!

Placing the DLL in `assets/plugins/FMOD` might not suffice, as FMOD expects platform specific subdirectories.

For example, on Windows, the typical path would be: **\Assets\Plugins\FMOD\platforms\win\lib\x86** , depending on your build architecture.

In Unity, go to **FMOD \> Edit Settings** , and under the **Plugins** section, make sure to enter the plugin name (without the `.dll` extension). You will also need to adjust the plugin’s import settings in Unity to ensure it matches the target platform and CPU architecture that the plugin was compiled for.

For a more detailed setup guide, please refer to this [documentation](https://fmod.com/docs/2.02/unity/plugins.html).

Hope this helps, let me know if the issue persists.
