2) Open the FaceFX asset for the character.
3) While leaving the FaceFX window open, select the newly created sound cue in the general browser.
4) In FaceFX, Go to Actor > Animation Manager. Click “Create Animation”.
5) After several confirmation screens, you will be prompted to enter the words of the sound file.
– Double-click any of the tabs to undock them from the main FaceFX Studio. Right-click and select close to restore.
