Adjust face stretch with open mouth

Heres a script by Ben that might help you out.

//This script allows you to stretch the face dynamically with mouth triggers. 
//When the user opens their mouth, the stretch increases at the speed you specify until it reaches the max amount that you specify (less than 2). 
//When the user closes their mouth, the intensity decreases to 0

// -----JS CODE----- 
// @input Component.FaceStretchVisual stretch 
// @input float intensityMax 
// @input float upSpeed 
// @input float downSpeed 
var feature = "Feature0"; 
var intensity = 0; 
var stretching = false; 
var openEvent = script.createEvent("MouthOpenedEvent"); 
openEvent.faceIndex = 0; 
openEvent.bind(function (eventData) 
{ 
stretching = true; 
stretch(); 
}); 
var closeEvent = script.createEvent("MouthClosedEvent"); 
closeEvent.faceIndex = 0; 
closeEvent.bind(function (eventData) 
{ 
stretching = false; 
stretch(); 
}); 
function stretch() 
{ 
var event1 = script.createEvent("UpdateEvent"); 
event1.bind(function (eventData) 
{ 
if (stretching) 
{ 
if (intensity < script.intensityMax) 
{ 
intensity += script.upSpeed; 
script.stretch.setFeatureWeight(feature, intensity); 
} 
else 
{ 
intensity = script.intensityMax; 
script.stretch.setFeatureWeight(feature, intensity); 
event1.enabled = false; 
return; 
} 
} 
else 
{ 
if (intensity > 0) 
{ 
intensity -= script.downSpeed; 
script.stretch.setFeatureWeight(feature, intensity); 
} 
else 
{ 
intensity = 0; 
script.stretch.setFeatureWeight(feature, intensity); 
event1.enabled = false; 
return; 
} 
} 
}); 

} 

Hey Takinours!

Like n-mikael mentioned above, that script should help you adjust the face stretch intensity. I also made a Youtube tutorial and template that you can download that implements the effect! Go ahead and check it out here - https://www.youtube.com/watch?v=iRjHo7i3ghc&list=PLW0Y_2Vl8nJ7JgVywfoOReQf5GbAKweVq&index=5

The link to the template is in the description!
