Exceptionally for this patch release, you will need to pay attention when migrating to Wwise 2018.1.2.

Upgrading Factory Asset Motion Presets Is Not Automatic

Users who already have Factory Asset Motion Presets in their 2018.1 or 2018.1.1 projects must delete two Work Units in their project in order to import the now revised Motion Presets:

• The Factory Motion Work Unit from the Actor-Mixer Hierarchy.
• The Factory Motion Work Unit from the Game Syncs tab's Game Parameters. Be careful to verify if there are project-specific changes under this Work Unit; these can be temporarily saved under another Work Unit to then reapply them, as desired, after importing the updated Motion Presets.
