Nvidia ACE 2.3 Audio2Face in Unreal Engine 5.4: Internal Plugin Bug: SessionID doesn't match

Hey there,

When I call the newly added function FACERuntimeModule::Get().AnimateFromAudioSamples multiple times with EndOfSamples argument being false, the first time it’s called it creates a valid session ID and plays the first animation, but then all the other calls get this error:

LogACERuntime: Warning: [ACE SID 3] internal plugin bug, SessionID doesn’t match -1

Does anyone know what could be the cause of this problem? Any potential fix?

Thank you!

Hi all, welcome to the NVIDIA developer forums.

I recommend checking out our Discord channel #ace-digital-humans since that is where most of the developer discussions are happening currently.

Thanks!
