Create wrap deformers

Creating a wrap deformer includes creating the objects you want to use as wrap influence objects, setting creation options, and then creating the wrap deformer.

Attention: Avoid changing the number of a deformable object’s points (for example, CVs, vertices, or lattice points) after you create a deformer. Changing the number of points can lead to unexpected deformation effects. Try to be sure you are happy with the deformable object’s topology before you begin using deformers. You might want to save a copy of the object in case you want to do further modeling later. You should also avoid changing the number of a wrap influence object’s points (CVs or vertices) after you create a wrap deformer.

Before you create a wrap deformer, create the objects you want to use as wrap influence objects.

Note: The time required to create a wrap deformer can vary depending on the resolution of the wrap influence object(s). The resolution can also affect the deformation calculation time as you manipulate the wrap deformer.

To create objects to use as wrap influence objects

1. Model one or more NURBS surfaces, NURBS curves, or polygonal surfaces that you want to use as wrap influence objects.

   Note that the shape and distribution of CVs or vertices can affect the wrap deformation effect. Typically, you would want to have fewer points (CVs, for example) in the influence object(s) than in the objects you want to deform.

2. Position the object or objects that you want to use as wrap influence objects. Place them around the object(s) you want to deform so that they can influence the object(s).
3. If you are going to use more than one object as a wrap influence object, group those objects together now. You must group all those objects together before you create the wrap deformer. However, note that you can also add wrap influence objects after you have created a wrap deformer. See Adding and removing wrap influence objects.

To create a wrap deformer

1. Select the object(s) you want to deform.
2. Select the previously created object or group of objects you want to use as wrap influence objects.
3. Select Deform > Wrap > .

   The Wrap Options window appears.

4. Set the creation options.

   See Wrap Options and Advanced deformer options.

5. Do one of the following:
   • Click Create to create a wrap deformer. The options close.

   Maya creates a wrap deformer node for each object you want to deform. Maya also creates wrap base objects for each wrap influence object. The Outliner lists the wrap base objects, which are hidden by default. Note that if you are using more than one influence object and have therefore grouped them together, the base objects are placed in the same group as the influence objects.

   The creation time can vary, depending on the number and resolution of the deformable objects and wrap influence objects.

   • Click Save to save creation options without creating a wrap deformer. The options window remains open.
   • Click Reset to reset to default creation options. The options window remains open.
   • Click Close to close the window.

To create wrap deformation effects

1. Move, rotate, or scale the wrap influence object(s).
2. Move the points of the wrap influence object(s).
3. Edit channels added to the wrap influence objects, and edit the channels of the wrap deformer(s).
