I am working on a VR project on Unity and from what I have read, I have to use Oculus spatializer in order to make FMOD work with Oculus. I have installed the Oculus plugin in FMOD and I have written down "OculusSpatializerFMOD" in the plugin section of FMOD settings in Unity, but I get an INVALID CHANNEL error in the console. How can I fix this? Is there a specific approach to use Oculus in FMOD?
