There are ways to add audio to your render in Unreal Engine, even if you use Movie Render Queue. This can be done with FFmpeg and the Movie Pipeline CLI Encoder. Below is a part of the documentation that mentions this.
That being said, we’ve concluded that currently, the documentation doesn’t fully cover this. The only documentation is from the FFmpeg project. We have concluded that participants may use post-software to add the audio to their render-we reserve the right to see a screen recording of the scene running inside Unreal Engine.
Please also keep in mind that audio is not an element that is being judged.
