I am working with UE4.15 and Wwise 2016.2.2.6022.
I think the function AK::SoundEngine::RegisterAllBuiltInPlugins() is deprecated.
In the file AllPluginsRegistrationHelpers.h,
/// This function is deprecated. All registration is automatic now. Kept for backward compatibility.
static AKRESULT RegisterAllPlugins()
RegisterAllBuiltInPlugins() is renamed as RegisterAllPlugins(), I think...
However, I still wonder how can I use the licensed plug-in.
Any help would be appreciated :)
