Skin > Edit Smooth Skin > Mirror Skin Weights

Mirror Across

Select one of the following options.

XY

Specifies mirroring weights about the global XY plane (the default).

YZ

Specifies mirroring weights about the global YZ plane.

XZ

Specifies mirroring weights about the global XZ plane.

Surface Association

Determines how the surface components on opposite halves of the skinned object correlate to each other.

Closest point on surface

Finds the closest points between the source and target surfaces and smoothly interpolates the skin weights at those points. This is the default setting.

Raycast

Uses a raycasting algorithm to determine sample points between the two surface meshes. This was the default smooth association in pre-8.5 versions of Maya.

Closest component

Finds the closest vertex component (polygons) or control vertex (NURBS) at each sampling point and uses its skin weight value without interpolation. This was the default non-smooth association in pre-8.5 versions of Maya.

Influence Association

Determines how the components that influence the skinned objects (that is, skeleton joints, influence objects, and so on) correlate between the source and destination objects.

The Influence Association occurs in a maximum of two iterations in order to determine the best correlation. You set the Influence Association type for each iteration from a drop-down list beside each level. Set the Influence Association type based on your knowledge of the two skinned objects being compared. As each iteration is completed, the next iteration continues using its specified Influence Association type on any remaining joints. If you are confident that only one iteration is required, you can set the other Influence Association level to None and it will not be occur.

Closest joint

Associates the joints that are in closest proximity to one another. This is the default setting for the first Influence Association.

One to one

Associates the joints in situations when the skinned objects have identical skeleton hierarchies.

Label

Associates the joints based on their pre-defined joint label. Joint label attributes can be set and edited in the Attribute Editor.

None

Specifies that no comparison will occur for that level of Influence Association.

Note

Reflection is disabled for the Paint Skin Weights Tool. Skin > Edit Smooth Skin > Mirror Skin Weights can be used as an alternative method to do reflection of the skin weights.
