  Q.

  I want to create a cutscene with multiple characters.
  In particular, I want to implement “Lip-Sync” where the character’s mouth changes according to the sound.

   

  A.

  If you want to make character animations play sequentially according to the scenario, it is convenient to use Unity’s Timeline.
  You can check the method of linking Timeline and AnyPortrait character in the following manual.
  https://rainyrizzle.github.io/en/AdvancedManual/AD_Timeline.html

   

  For lip syncing, you’ll need to use a little script.
  Write a MonoBehaviour script with the following code:

  public class LipSyncScript : MonoBehaviour
  {
          public apPortrait portrait;
          public float mouthValue;

          void Update()
          {
                portrait.SetControlParamFloat(“Mouth Open”, mouthValue);
          }
  }

  This is to make the mouth of the AnyPortrait character change according to the control parameter called “Mouth Open”, and then use a script to change the value of the control parameter every frame.

  And register the GameObject with this script to the Timeline, and control the “mouthValue” value.
  This way, the value of “mouthValue” animated by the Timeline will be passed to the AnyPortrait character, so as a result, you can control the character’s mouth with the Timeline.
