Note: This integration does not support experimental Unreal Engine features.

Note: This integration was compiled against Unreal Engine version 4.27, 5.2, 5.3, and 5.4. It was tested against Unreal Engine 5.4. Deprecation Notice: Support for Unreal Engine 4.27 will be removed in a future minor release. We recommend that you use Unreal Engine 5.2 or later.
