Adding Lip-Sync to your Character
To add Lip-Sync to your character, follow these steps.
Convai's Lip-Sync uses OVR or Reallusion CC4 Extended (Reallusion CC4+) Blendshapes. The lip-sync will work best with models that have OVR or Reallusion CC4 Extended (Reallusion CC4+) compatible Blendshapes.
Select the character GameObject and click Add Component in the Inspector.

Select
Convai Lip Sync
to add the Lip Sync component.
In the new component, select the type of lipsync, and assign the Skinned Mesh Renderer with the Facial Blendshapes (here for Reallusion Characters,
CC_Base_Body
, CC_Base_Teeth
and CC_Base_Tongue
) and the game objects corresponding to the bones for Jaw and Tongue (here for Reallusion Characters, CC_Base_JawRoot
and CC_Base_Tongue01
). Feel free to adjust the position of the tongue with the Tongue Bone Offset field. Currently, only Reallusion Plus and OVR are supported as a type of lip sync.

If your character's mouth seems to not be opening enough for a proper lip sync, this could indicate an issue with the animator or animations.
To resolve common issues caused by the animator and animations, follow the troubleshooting guides below.
