# Class: FaceControls

> The [FaceControls](/docs/reference/engine/classes/FaceControls.md) object defines a set of properties for controlling
> the facial expressions of a Dynamic Head.

## Description

The [FaceControls](/docs/reference/engine/classes/FaceControls.md) object defines a set of properties for controlling
the facial expressions of a character head capable of animation.

The FaceControls properties are based on the Facial Action Coding System
(FACS), a comprehensive system for describing all visually discernible facial
movement based on anatomy. [FaceControls](/docs/reference/engine/classes/FaceControls.md) properties can only be set
between 0 and 1. Different combinations of the [FaceControls](/docs/reference/engine/classes/FaceControls.md) property
values create different facial expressions. Recording multiple facial
expressions over time creates facial animation.

## What is an Animatable Head?

An animatable head is a [MeshPart](/docs/reference/engine/classes/MeshPart.md) that implements a facial rig and is
capable of playing facial animations and triggering facial expressions. A
[FaceControls](/docs/reference/engine/classes/FaceControls.md) object that is a child of a head [MeshPart](/docs/reference/engine/classes/MeshPart.md) can
change the facial expressions of the head.

A head consists of the following three components:

- Skinned MeshPart instance for the head geometry with an internal rig that
  deforms this skinned MeshPart
- FaceControls instance that drives the internal rig when properties such as
  FaceControls.JawDrop are changed.
- Cage [WrapTarget](/docs/reference/engine/classes/WrapTarget.md) instance for tight fitting facial accessories

In a third-party modeling tool, such as Blender or Maya, an artist can create
a joint-driven facial rig, pose the joints to match each of the individual
FACS controls, and save as an FBX. When a head `.FBX` is imported in Studio, a
facs-to-joint mapping is created. This mapping deforms the mesh geometry when
FaceControls properties are changed. The mapping and the facial rig (including
[Bone](/docs/reference/engine/classes/Bone.md) instances) are not exposed to developers and can only be accessed
through the FaceControls instance. The [MeshPart](/docs/reference/engine/classes/MeshPart.md) for a Dynamic Head
looks and behaves the same as a regular [MeshPart](/docs/reference/engine/classes/MeshPart.md) except when a
FaceControls instance is a child of the MeshPart. Editing the properties of
the FaceControls deforms the MeshPart's geometry. These properties are
available to animate in the Animation Editor.

See [Facial Animation](/docs/en-us/art/characters/facial-animation.md) for
more information on usage and creation of an animatable head.

## Animatable Heads in the Marketplace

If you are publishing your head to the Marketplace, your head asset must
include a minimum subset of face controls. Roblox's publishing validation
rejects assets without the following required poses:

- EyesLookDown
- EyesLookLeft
- EyesLookRight
- EyesLookUp
- JawDrop
- LeftEyeClosed
- LeftLipCornerPuller
- LeftLipStretcher
- LeftLowerLipDepressor
- LeftUpperLipRaiser
- LipsTogether
- Pucker
- RightEyeClosed
- RightLipCornerPuller
- RightLipStretcher
- RightLowerLipDepressor
- RightUpperLipRaiser

See
[FACS pose reference](/docs/en-us/art/characters/facial-animation/facs-poses-reference.md)
for more information on usage and creation of an animatable head.
