WrapDeformer

Inherits from: BaseWrap → Instance → Object

The WrapDeformer object provides a low-resolution cage mesh that pairs with a WrapTarget sibling to deform a parent MeshPart. The MeshPart geometry is deformed according to the displacement between pairs of WrapTarget cage mesh vertices and WrapDeformer cage mesh vertices. Cage mesh vertices are paired based on UV equivalence.

WrapDeformer may be used with avatars or on distinct MeshParts, as long as WrapTarget children are present for the parent MeshParts. WrapDeformer is similar to WrapLayer but doesn't require layered clothing and can directly deform MeshParts for publishing.

WrapDeformer:CreateEditableMeshAsync

Constructs and returns an EditableMesh corresponding to the deformed parent mesh geometry. This method respects all updates made to the deformation inputs prior to the request. It also sets the returned result's FixedSize to true.

Returns

TypeDescription
EditableMeshAn EditableMesh matching the deformed parent mesh geometry, with its FixedSize set to true.
FieldValue
tags["Yields"]
securityNone
thread safetyUnsafe
capabilities["AvatarAppearance"]

WrapDeformer:GetDeformedCFrameAsync

Returns a CFrame deformed by the same deformation field used for the geometry of the parent MeshPart. This method is useful for the placement of accessories.

The input and output CFrame are both in the space of the parent MeshPart; only position (not rotation) will be deformed. This method respects all updates made to the deformation inputs prior to the request.

Parameters

NameTypeDefaultDescription
originalCFrameCFrameThe CFrame, expressed in the local space of the parent MeshPart, whose position is deformed.

Returns

TypeDescription
CFrameA CFrame in the parent MeshPart space with its position displaced by the same deformation field applied to the parent mesh; rotation is unchanged.
FieldValue
tags["Yields"]
securityNone
thread safetyUnsafe
capabilities["AvatarAppearance"]

WrapDeformer:SetCageMeshContent

Sets the cage mesh used to deform the parent MeshPart in conjunction with a sibling WrapTarget cage mesh. The content parameter should represent a Roblox mesh asset ID or an EditableMesh reference in your DataModel.

Parameters

NameTypeDefaultDescription
contentContentA Roblox mesh asset ID or an EditableMesh reference specifying the cage mesh to deform against the sibling WrapTarget.
cageOriginCFrame?An optional CFrame, in the parent MeshPart space, that sets the cage's CageOrigin. When omitted, the existing CageOrigin is left unchanged.

Returns

TypeDescription
()
FieldValue
securityNone
thread safetyUnsafe
