PatchDeform Modifier (World Space)

Select an object. > Modify panel > Modifier List > World-Space Modifiers > * PatchDeform

The PatchDeform world-space modifier lets you deform an object based on the contours of a patch object. It works the same as the PathDeform (World Space), but uses a patch instead of a curve. With the exception of the Move to Patch button, its parameters are the same as those in the object-space PatchDeform modifier.
