Movie Render Queue, No Audio?

Question

Hi folks,

I've run into a problem on our project. We're currently using the Movie Render Queue plugin to render our level sequence cinematics out of Unreal Engine. The problem we are facing is that even though we've selected ".wav audio" as an output in the settings, no audio is being rendered. if we render locally it outputs a .wav file that is silent for the duration of the clip, if we render remotely it doesn't output a .wav file at all.

We are using AkAudioEvent on the level sequence as normal, the soundbank is generated and loaded correctly, when you start rendering you can hear the audio being played as it's rendered. Has anyone else run into this problem. Does anyone know the answer to this?

We are currently on Unreal Engine 5.1.1 and Wwise 2022.1.5.

Cheers,

Sam

I am also very interested in solving this.

Answer 1

After researching this on my end and consulting with the audio programming team at Epic, the path here is
1. Modify UE engine so that the offline audio rendering path supports external APIs to hook into it to provide their own implementations of offline audio mixers

2. Epic would likely accept this as PR to the engine

3. Audiokinetic needs to provide their own implementation of an offline audio device and offline audio mixer.

Question is, would AK be willing to work on a PR to the UE engine to make it open for external extension.
