--- name: BodyPartDescription last_updated: 2026-06-11T23:11:56Z inherits: - Instance - Object type: class memory_category: Instances summary: "Describes the appearance of an avatar body part for the HumanoidDescription." --- # Class: BodyPartDescription > Describes the appearance of an avatar body part for the > [HumanoidDescription](/docs/reference/engine/classes/HumanoidDescription.md). ## Description **BodyPartDescription** is an object that stores the description for an avatar's body parts, such as the [Color](/docs/reference/engine/classes/BodyPartDescription.md). It is meant to be placed underneath a [HumanoidDescription](/docs/reference/engine/classes/HumanoidDescription.md) in order to work with [Humanoid:ApplyDescriptionAsync()](/docs/reference/engine/classes/Humanoid.md). ## Properties ### Property: BodyPartDescription.AssetId ```json { "type": "int64", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Data", "capabilities": [ "AvatarAppearance" ] } ``` The asset ID that should be applied when applying this [BodyPartDescription](/docs/reference/engine/classes/BodyPartDescription.md). ### Property: BodyPartDescription.BodyPart ```json { "type": "BodyPart", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Data", "capabilities": [ "AvatarAppearance" ] } ``` The type of body part. ### Property: BodyPartDescription.Color ```json { "type": "Color3", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Data", "capabilities": [ "AvatarAppearance" ] } ``` The [Color3](/docs/reference/engine/datatypes/Color3.md) for this body part. ### Property: BodyPartDescription.HeadShape ```json { "type": "string", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Data", "capabilities": [ "AvatarAppearance" ] } ``` **HeadShape** specifies a Classic Head shape identifier to apply to a compatible Dynamic Head. This property is only relevant when [BodyPart](/docs/reference/engine/classes/BodyPartDescription.md) is set to [Head](/docs/reference/engine/enums/BodyPart.md) and [AssetId](/docs/reference/engine/classes/BodyPartDescription.md) references a Dynamic Head that supports head shapes. #### Example ```lua local AvatarEditorService = game:GetService("AvatarEditorService") -- Get available head shapes for the user local headShapes = AvatarEditorService:GetHeadShapesAsync(userId) -- Create a BodyPartDescription for a Dynamic Head with a Classic shape local bodyPartDescription = Instance.new("BodyPartDescription") bodyPartDescription.BodyPart = Enum.BodyPart.Head bodyPartDescription.AssetId = dynamicHeadAssetId bodyPartDescription.HeadShape = headShapes[1] -- Apply the first owned head shape bodyPartDescription.Parent = humanoidDescription -- Apply the description humanoid:ApplyDescriptionAsync(humanoidDescription) ``` See also: - [AvatarEditorService:GetHeadShapesAsync()](/docs/reference/engine/classes/AvatarEditorService.md), which returns head shape identifiers that can be used with this property - [AssetId](/docs/reference/engine/classes/BodyPartDescription.md), which specifies the Dynamic Head asset to apply the shape to - [BodyPart](/docs/reference/engine/classes/BodyPartDescription.md), which must be set to [Head](/docs/reference/engine/enums/BodyPart.md) for this property to have effect - [Humanoid:ApplyDescriptionAsync()](/docs/reference/engine/classes/Humanoid.md), which applies the description containing this [BodyPartDescription](/docs/reference/engine/classes/BodyPartDescription.md) ### Property: BodyPartDescription.Instance ```json { "type": "Instance", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Data", "capabilities": [ "AvatarAppearance" ] } ``` A reference to the [Instance](/docs/reference/engine/classes/Instance.md) that should be applied when applying this [BodyPartDescription](/docs/reference/engine/classes/BodyPartDescription.md). This property can be used instead of [AssetId](/docs/reference/engine/classes/BodyPartDescription.md) to apply accessories without uploading them to the platform. This can reference either a body part with R15, **R15ArtistIntent** and **R6** folders, or only reference a single subfolder. ## Inherited Members ### From [Instance](/docs/reference/engine/classes/Instance.md) -
