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.
- Direction
-
Positive to Negative (+Z to
-Z) specifies direction of the mirroring along the specified Mirror Across 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.
