I’m not getting Oculus spatialiser linking between FMOD and UE4 on Win10.
I have regular (non-Oculus) 3D sound working fine through Rift S.

As instructed here How to Use the Oculus Spatializer in FMOD Studio: Unreal | Oculus Developers I have my OculusSpatializerFMOD.dll (with text file ‘OculusSpatializerFMOD’) sat next to my fmod.dll files in UE4.26 > Engine > Plugins > FMODStudio > Binaries > Win64 but the OculusSpatializerFMOD doesn’t appear as per this image:

In UE4 the Oculus-Spatialized event sometimes appears as ‘3D - False’ in details, other times ‘True’ with 0 min and max, not sure where it’s getting 0 from. Leyland 4 98 engine manual.

Oculus Spatializer Vst Plugin

Other stuff I’ve tried:

• The problem is that you still need the Oculus integration for the stuff related to Oculus Platform (Entitlements.cs) and the Oculus Spatializer (OculusSpatializerUnity.cs). Plus, there's stuff like the OVRHand (OVRHand.cs) which you need for hand tracking to work, which only exists in the Oculus integration.
• The Oculus Spatializer Plugin for DAWs is a new addition to the Audio SDK that bridges this gap in sound design workflow. It allows sound designers to preview 3D spatialized sounds during the design phase, before their content reaches the audio middleware or game engine level, thus tightening the iteration loop between design and production.

Oculus Spatializer package for Unity (we’ve downloaded it already) Go ahead and import the integration for Unity, like any other package: double click on it while you have Unity opened in the background. Now do the same think with the package you’ll find in the Spatializer folder. This guide describes how to install and use the Oculus Spatializer VST plugin with the Oculus Rift. For an overview of all of the audio tools offered by Oculus, see Working with Audio in Unity. For general background information on audio spatialization, see our Introduction to Virtual Reality Audio. VST Spatializer topics.

Extractor mac. guide from - Set Up the Oculus Spatializer Plugin (OSP) for FMOD: Unity | Oculus Developers (no idea where mysterious 'Oculus Spatializer folder > AudioSDKPluginsFMODx64 folder is, i assume it’s same x64 folder from the download ZIP in ‘ovr_audio_spatializer_fmod’ folder)

Oculus Spatializer Unity

The Legacy Oculus Spatializer that comes with version 1.0.1 of the Oculus Audio SDK sounds just fine. I also found some other strange behavior with the Oculus Native Spatializer that is possibly related: You can distort and even invert the HRTF by messing with the scale of the main camera (or whatever GameObject has the Audio Listener attached).

in FMOD > Oculus plugin instead of spatializer on each event master track, mono in, stereo out
mixer master bus stereo out (tried both stereo and 5.1 in) and have Oculus Spatial Reverb

Oculus Spatializer Wwise

in UE4 > Platforms > Win > Audio > Spatialization and Reverb Plugin > Oculus Audio, and Plugins > Oculus Audio > enable Late Reverberation, Plugins > FMOD Studio > Output Format Stereo Recon marine armor fallout 4.

any help much appreciated, thanks.
