FACS Poses Reference

The Facial Action Coding System (FACS) is a comprehensive, anatomically-based system for describing all visually discernible facial movement. This system breaks down all facial expressions into individual types of muscle movement, such as LeftEyeClosed or MouthLeft. You can configure and store these muscle movements, or poses, within the head model through a third-party modeling software, such as Blender or Maya. When you import the head model into Studio, you can then access and animate these poses to create lively facial expressions.

The following is a list of 50 base poses that you can use in Roblox to portray a wide range of face emotions. You can combine 2-3 FACS base poses together in one animation frame to create complex facial expressions, but if the base poses control the same facial regions, the facial features might collide unless you also add a corrective to their full default values.

ChinRaiser

ChinRaiser raises the chin up; moves the lower lip upwards.


When you use ChinRaiser when the character's mouth is closed, the character's lower lip collides with their upper lip. When you need to keep the mouth closed while raising the chin, use ChinRaiserUpperLip and ChinRaiser together to raise both the lower and upper lip, and avoid a collision. Note that if you use this method, you must set both ChinRaiser and ChinRaiserUpperLip to the same value so the lips move the same distance upwards.

LipsTogether

LipsTogether brings the character's lips together. However, if the character's mouth is closed, their lips are already together and the lips collide with each other.


This pose's main use case is in connection with the JawDrop property. If you set JawDrop and LipsTogether to 100% of their default values, the character's lips stay together as the jaw drops.


In addition, if you set JawDrop to 100% of its default value, and ease LipsTogether in and out of 100% of its default value, the character's lips open and close.


MouthLeft

MouthLeft moves the mouth to the character's left. This property doesn't move the character's jaw, teeth, or tongue, only their mouth. If you want to move those additional facial features, use JawLeft instead.
