Note: This integration was compiled against Unreal Engine version 4.27, 5.0, and 5.1. It was tested against Unreal Engine 5.1. Any major Unreal Engine version more recent than the aforementioned is not currently supported, but will be in a subsequent patch release.

New Features

• WG-62790 Added official support for Unreal Engine 5.1.

• WG-63770 Added uMaxSystemAudioObjects to the Advanced Initialization Settings based on new functionality provided by the Wwise SDK.
