Wrinkle Deformers

The wrinkle deformer consists of one or more wire deformers. It automatically creates the wires and combines them under a cluster handle, providing you with a quick and easy way to create wrinkles on a surface.

The wrinkle deformer has options for creating radial wrinkles, which branch out from a center point, and tangential wrinkles, which run parallel to each other along the surface. You can also use the Custom type to create wrinkles based on preexisting NURBS curve(s).

To create a wrinkle deformer:

1.	Select the surface you want to deform.
2.	From the Deform menu, choose the box next to Wrinkle Tool. The Wrinkle tool options appear, and a UV region is displayed on your model.
3.	In the Wrinkle tool settings, choose the Type, and adjust any other settings you'd like to change (Figure 13.47). Figure 13.47. The Wrinkle tool settings let you determine what type and number of wrinkles will be created on your surface.
4.	In the view, click and drag with the middle mouse button on the control points of the UV region. The points on the edges let you resize it, the points on the corners let you rotate it, and the point in the middle lets you position it (Figure 13.48). Figure 13.48. By modifying and repositioning this UV region, you can determine what area of your surface is affected by the wrinkle deformer.
5.	Press . A cluster handle appears over the object.
6.	Select and move the cluster handle. The surface wrinkles in the area you've selected (Figure 13.49). Figure 13.49. Moving the cluster handle causes the wrinkles created by the wrinkle deformer to appear on the surface of your object.

Tips

• If you're looking for the wires created by the wrinkle deformer, you can view and select them in the Outliner, under their associated clusterHandle. You can display them by choosing Display > Show > Show Selected or by setting their Visibility to On in the Channel Box. As with the wire deformer, you can manipulate a wire's CVs to deform the surface.
