Synopsis

copySkinWeights([destinationSkin=string], [influenceAssociation=string], [mirrorInverse=boolean], [mirrorMode=string], [noBlendWeight=boolean], [noMirror=boolean], [normalize=boolean], [sampleSpace=uint], [smooth=boolean], [sourceSkin=string], [surfaceAssociation=string], [uvSpace=[string, string]])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

copySkinWeights is undoable, queryable, and editable.

Return value

None

In query mode, return type is based on queried flag.

Flags

Long name (short name)	Argument types	Properties
sourceSkin(ss)	string
Specify the source skin shape
destinationSkin(ds)	string
Specify the destination skin shape
normalize(nr)	boolean
Normalize the skin weights.
noMirror(nm)	boolean
When the no mirror flag is used, the weights are copied instead of mirrored.
mirrorInverse(mi)	boolean
Values are mirrored from the positive side to the negative. If this flag is used then the direction is inverted.
smooth(sm)	boolean
When the smooth flag is used, the weights are smoothly interpolated between the closest vertices, instead of assigned from the single closest.
mirrorMode(mm)	string
The mirrorMode flag defines the plane of mirroring (XY, YZ, or XZ) when the mirror flag is used. The default plane is XY.
surfaceAssociation(sa)	string
The surfaceAssociation flag controls how the weights are transferred between the surfaces: "closestPoint", "rayCast", or "closestComponent". The default is closestComponent.
influenceAssociation(ia)	string
The influenceAssociation flag controls how the influences on the source and target skins are matched up. The flag can be included multiple times to specify multiple association schemes that will be invoked one after the other until all influences have been matched up. Supported values are "closestJoint", "closestBone", "label", "name", "oneToOne". The default is closestJoint.
sampleSpace(spa)	uint
Selects which space the attribute transfer is performed in. 0 is world space, 1 is model space. The default is world space.
uvSpace(uv)	[string, string]
The uvSpace flag indicates that the weight transfer should occur in UV space, based on the source and destination UV sets specified.
noBlendWeight(nbw)	boolean
When the no blend flag is used, the blend weights on the skin cluster will not be copied across to the destination.

Flag can appear in Query mode of command	Flag can have multiple arguments, passed either as a tuple or a list.
