This will work on any avatar - you just have to position it

Puffiness has a slider, gape has a toggle for enabling/disabling. Size needs to be adjusted in the editor by scaling the armature, this is just so that it keeps the calibration consistent for the auto-dilation

If you’d like to calibrate the gape settings uniquely it can be changed in the blendtree that handles it although this requires some knowledge of the Unity animator. I can always be reached through email for any help with this, though.
