# FACS poses reference

The [Facial Action Coding System](https://en.wikipedia.org/wiki/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](/docs/en-us/art/characters/facial-animation/create-basic-heads.md#pose) and store these muscle movements, or **poses**, within the head model through a third-party modeling software, such as [Blender](https://www.blender.org) or [Maya](https://www.autodesk.com/products/maya/overview). When you import the head model into Studio, you can then access and [animate](/docs/en-us/art/characters/facial-animation/animate-heads.md) 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. Except for the first neutral pose, the order of poses you save to your character model doesn't matter since this information is set during the [mapping](/docs/en-us/art/characters/facial-animation/create-basic-heads.md#map) process as a custom property.

> **Warning:** If you intend to publish your avatar to the Marketplace, your avatar head must include the required [17 facial base poses](/docs/en-us/avatar/character-bodies/specifications.md#facial-animations). Marketplace validation rejects assets that do not include these 17 required base poses.

You can combine multiple FACS base poses together in one animation frame to create complex facial expressions. However, some combinations of poses might collide unless you also add a [corrective](/docs/en-us/art/characters/facial-animation/create-basic-heads.md#combination-poses) to their full default values.

## LeftEyeClosed

> **Warning:** If publishing to the Marketplace, your avatar asset must include this pose.

`Class.FaceControls.ChinRaiser|ChinRaiser` raises the chin up; moves the lower lip upwards.

When you use `Class.FaceControls.ChinRaiser|ChinRaiser` and 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`](#chinraiserupperlip) and `Class.FaceControls.ChinRaiser|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 `Class.FaceControls.ChinRaiser|ChinRaiser` and [`ChinRaiserUpperLip`](#chinraiserupperlip) to the same value so the lips move the same distance upwards.

## ChinRaiserUpperLip

> **Warning:** If publishing to the Marketplace, your avatar asset must include this pose.

`Class.FaceControls.ChinRaiserUpperLip|ChinRaiserUpperLip` raises the upper lip up when ChinRaiser is engaged and it is touching the upper lip.
