Hi,  
I’m trying to set occlusion details on several events,  
It was easy to set on FMODAudio Component (Play Event Attaced).

However, as for FMOD Event Instance (Play Event at Location), I can’t set it because "FMODEvent Instance Structure is not compatible with FMODAudio Component Pbject Reference.

Using the ‘occlusion details’ is a function of the `FMODAudioComponent` specifically and `PlayEventAtLocation` doesn’t use that, it directly makes an event at a specified location and returns the instance.

Hi, Thanks,  
I understand it returns the instance.  
So, It means… If I want to use Occlusion feature, I must use FMODAudioComponent, not the instance. Right?  
Then, is there any way to spawn a FMODAudioComponent at Location (not attach something) ?

Other than `PlayEventAttached` you can use the `Add FMODSudio Component` node to spawn a component.
