- Exclusive bind
-
When
on, the wrap deformer’s target surface will behave like a rigid
bind skin and Weight Threshold is disabled.
Each surface point on the wrap deformer’s target surface will only
be affected by a single wrap influence object point.
NoteExclusive bind only
works with polygon mesh target surfaces.
- Auto Weight Threshold
-
When
on, the wrap deformer automatically sets the optimal weight of the
wrap influence objects’ shapes by calculating the smallest Max Distance value
that will ensure every point on the mesh is affected by an influence
object. This option is on by default.
- Weight Threshold
-
Lets
you manually specify the influence of the wrap influence objects’
shapes based on the proximity of their components to the objects being
deformed. Depending on the point density (for example, the number
of CVs) of the wrap influence objects, changing the Weight Threshold can
change the overall smoothness of the deformation effect. Values
range from 0.000 (smooth) to 1.000 (sharp). Use the slider to select
values from 0.000 to 1.000. Default is 0.000.
NoteWeight
Threshold, Use Max Distance, and Max
Distance are only available when Auto Weight
Threshold is turned off.
- Use Max Distance
-
Turn Use
Max Distance on if you want to set the Max
Distance value and limit the influence area.
- Max Distance
-
Specifies
the influence area of wrap influence object points. By limiting
the influence area with Max Distance,
you can manually limit how much memory Maya requires to perform
the deformation. The less memory required, the better the performance.
Using Max Distance is especially
useful when you are working with high-resolution wrap influence
objects.
NoteThe Weight
Threshold takes effect within the influence area defined
by the Max Distance value.
The Max
Distance value is in Maya’s working units, which are
by default centimeters (Window > Settings/Preferences
> Preferences > Settings > Working Units). The
default Max Distance is 1, limiting
the influence area to within a distance of 1 unit from each point, which
requires less memory. A Max Distance of 0
means the influence area is infinite. This setting will use the
maximum amount of memory.
The Auto
Weight Threshold value provides a good starting weight
for the minimum cutoff. If the deformation is not satisfactory using
this value, you can turn off Auto Weight Threshold and
adjust the Weight Threshold manually.
To find the best value, start by using the Auto Weight
Threshold value that displays in the Attribute
Editor, then gradually reduce the value until the deformation
is satisfactory.
- Render Influence Objects
-
Sets whether the wrap
influence objects are rendered or not. When on, the wrap influence objects
are visible if you render the scene, and when off, they are not
visible when you render.
TipYou
might want to render the wrap influence object, for example, if
you use a cloth garment as a wrap influence object and want to render
both the action of the garment and the wrap deformer’s effects.
Falloff Mode
Select
from the following options.
- Volume
-
Sets the
wrap deformer to use direct distances to calculate weights for the
wrap influence objects. This is the default.
- Surface
-
Sets the deformer to
use surface-based distances to calculate the weights. Using this
mode, you can create wrap deformer effects such as a mouth with
the upper and lower lips moving independently.
NoteIf you are working
with dense geometry, setting the Falloff Mode to Surface can
have a negative impact on performance as it requires more resources
to calculate the surface-based deformation.
