Edit

Blend Shape

Select Deform > (Edit) Blend Shape > to opens the Blend Shape Rollout, where you can select:

• Blend Shape Add Options
• Blend Shape Remove Options
• Blend Shape Swap Options
• Blend Shape Bake Topology to Targets
• Blend Shape Edit Normalization Groups

See Shape authoring and Create blend shape deformers for general information on blend shape deformations.

Lattice

Select Deform > (Edit) Lattice > to opens the Lattice Rollout, where you can select:

Remove Lattice Tweaks

Changes the number of divisions on a lattice whose points have been moved, choose Remove Lattice Tweaks, and then change the divisions of the lattice. If you want to change the divisions on a lattice with history, find the input lattice shape and change its divisions. You can find the input lattice by selecting the lattice and looking in the attribute editor tabs for the original lattice shape, which will typically share the same base name as the output lattice appended by “Orig.”

Reset Lattice

Resets the lattice. However, you cannot change the resolution of a lattice if the lattice points have been moved from their reset position or the lattice has history.

See also Edit Lattice deformers.

Wrap

Select Deform > (Edit) Wrap > to opens the Wrap Rollout, where you can select:

Add Influence

Adds the selected object as a new influence for the specified wrap deformation.

Remove Influence

Removes the selected influence object from the specified wrap deformation.

See also Edit Wrap deformers.

ShrinkWrap

Select Deform > (Edit) ShrinkWrap > to opens the ShrinkWrap Rollout, where you can select:

Add Surfaces

Adds NURBs surfaces to the existing deformer.

Remove Inner Object

Removes the connection between the inner object and the wrapper object without deleting the shrinkwrap node. When you remove an inner object, it no longer affects the wrapper object.

Remove Surfaces

Removes NURBs surfaces from the existing deformer.

Remove Target

Removes the connection between the target object and the wrapper object without deleting the shrinkwrap node. When you remove a target, it no longer affects the wrapper object.

Set Inner Object

Lets you reset your inner object after you've created a shrinkwrap deformer in your scene.

Set Target

Lets you reset your target object after you've created a shrinkwrap deformer in your scene.

Membership

Edit Membership Tool

You can directly edit deformer set memberships by selecting deformable object points with the Set Membership Tool.

See Edit deformer set membership and Paint Set Membership Tool.

Prune Membership

Opens the Prune Membership menu.

You can remove unaffected points from a deformer set based on which points the deformer is affecting. Use this to avoid unnecessary calculations for points that are not being affected by the deformation. Prune Membership is available for only Cluster, Lattice, Sculpt, and Wire deformers

The pruning operation considers only the current position of each component in the undeformed and deformed versions of the geometry affected by the specified deformation. If you have animated attributes of your deformation, the pruning operation is performed based only on the current attribute values. This means that components that are potentially affected at other frames of your animation might get pruned out if they are unaffected at the current frame.

Since a typical blend shape operation has weights of 0.0 for some target shapes at any point in time, this operation is especially dangerous when applied to blend shape deformations. For this reason, there is no menu item provided to prune membership for blend shape deformers. However, you can access prune membership for blend shape deformers through the command line.

See:

• To prune Cluster deformer set membership
• To prune Lattice deformer set membership
• Pruning sculpt deformer sets in the Editing sculpt deformation effects topic
• Prune Wire deformer sets in the Edit Wire deformers topic

Intermediate Objects

Display Intermediate Objects

Turns on the visibility for the current object’s original (prior to deformation) shape. You can use intermediate objects as points-of-reference when deforming objects. For example, you can compare a deformed object and its intermediate object to determine how different the deformed object is from its original shape.

See also Displaying and hiding intermediate objects.

Hide Intermediate Objects

Turns off the visibility for the current object’s original (prior to deformation) shape.

See also Displaying and hiding intermediate objects.

Export Weights

Opens the Export Deformer Weights Options, where you can set the options for exporting deformer weights as an XML or JSON file.

Existing nodes

Lets you select from a drop-down list of the deformer nodes in your scene.

File Format

Lets you save the weights in XML or JSON file format.

File name

Enter a file name for the weight map. By default the weight map is saved to your current project directory. Click the folder icon to browse to a different directory.

See also Export and import deformer weights.

Import Weights

Opens the Import Deformer Weights Options, where you can select a file containing the deformer weight map you want to import.

Deformer node

Lets you enter the name of the node where you want to import the weights. You can also select the node from the Existing nodes list.

Existing nodes

Select from a drop-down list of the deformer nodes in your scene.

File name

Enter the name of the XML file you want to import, or click the folder icon to browse and select a file.

Mapping Method

This drop-down menu lets you select from the following options:

Index

Replaces current values on the skinned object with the imported values taken from the XML file, overwriting values only for vertices that match between the mesh and imported weights file (for example vertex1 on mesh to vertex1 of the imported XML file.)

Select this option if you want the import to rely on the index of the vertex in the deformer. This is useful for getting a perfect match between shape nodes and deformers.

Over

Replaces current values on the skinned object with the imported values taken from the XML file, overwriting any default values for weights.

Nearest

Select this option if you want Maya to determine which point gets what weights based on the proximity of the point in the weight map. This can be useful when the index numbers have changed but the topology is very similar or exact.

Ignore names

When on, Maya ignores the names of the deformer nodes when trying to import weights.

Normalize Weights

When on (by default), Maya completes an extra normalization pass while importing the weight values in order to prevent jagged artifacts from appearing on the target mesh. In some cases, these artifacts can occur after weight values are rounded on export.
