Post event at location. Position relative to listener remains static.

Question

Hi. When posting an event on location in UE4 the sound triggered will not update it's relative position to the listener.

Example: When starting a fire (looping sound) at a location, the stereo spread and volume will remain constant even though the listener moves towards or away from the looping event.

It is like Post event at location creates a snapshot of the location and position of the listener upon activation and then ignores any changes.

I realize that the node itself says "Fire and forget", is this what that actually means?

You're right, there is an issue with Post Event at Location and 3D sound. We are currently tracking this issue, and it will be fixed in an upcomming release.

As for your use case, I would advise you to use an AkAmbientSound for it. You will have more control on its attenuation radius, occlusion, etc. Post Event At Location really is a Fire and Forget type of method; it would be more suitable for footsteps or bullet impacts, for example.
