This script streamlines the process of creating deformable controls that were demonstrated by Pixar in one of their demos. Here's a demo of how the tool works: https://vimeo.com/102143015
Copy the "rr_deformableControls" folder to your scripts directory. You can check your scripts directory by typing "internalVar -usd;" in the command line.
Execute in ScriptEditor (in a Python tab):
from rr_deformableControls import core c = core.deformingControls() c.ui()
You can highlight those lines and middle click and drag it to your shelf to create a shelf button.
Once that's done, all you need to do input your mesh (the deforming mesh) in the "mesh" field using the "<d like to keep the current control curves, turn it off to replace all the shapes in the control.
