Migration Notes 2017.2.0.6500.836

Migrating to the UE4.17/4.18 Wwise 2017.2.0 integration

A coordinate system conversion has been removed from the 2017.2.0 integration. This conversion was put in place to convert from the left-hand axis system used in Unreal Engine 4 (with the X and Y axes being the floor) to the default left-hand system used in Wwise Game Object 3D Viewer (with the X and Z axes being the floor). In order for the Wwise Game Object 3D Viewer to properly display Game Objects from Unreal, please go to the Game Object 3D Viewer settings and set the Floor Plane to X-Y:

Migrating Ak Acoustic Portal objects

Please note that in Wwise 2017.2.0, Spatial Audio Portals have a distinct orientation. The Portal's local Y-axis is the axis along which two adjacent Rooms are linked. It will be necessary to examine all existing Portals, and rotate (by 90 degrees, along the Z-axis) those that are not properly aligned in order to link Rooms along the Y-axis. A new visualization component has been added to the Portals to make the orientation of the Portal immediately apparent to the user. Portals that are incorrectly aligned may behave unexpectedly or return errors when sent to Wwise Spatial Audio.
