cvShapeInverter (3.9 KiB, 1,024 hits)

Description

A script and deformer that can invert a shape through a deformation chain so the shape can be applied as a front of chain shape. This has the same functionality as Christian Breitling’s correctiveShape plug-in. He stopped providing it after Maya 2008 so I’m providing a Python version that doesn’t need to be compiled.

Installation

Copy the contents of the scripts folder into your Maya scripts directory. Copy the contents of the src directory into your Maya plug-ins directory.

Usage Notes

Pose your skinned model in the pose that you want to correct. Duplicate the mesh and sculpt in your fixes. Select the original skinned model, shift select the corrected model and run:

import cvShapeInverter
cvShapeInverter.invert()

An inverted shape will be generated which you can then apply as a front of chain blendShape target. The generated shape will have a live deformer affecting it so edits you make on your corrected mesh will be inverted through the deformer.

Thanks a lot for this! Found this through the link on Scott’s site. I’ve repurposed Christian’s MEL script into a Python version, and I’ve been meaning to turn it into a deformer but haven’t had the time. Thanks for making this!

thanks Chad. I have some troubles trying to install .Do a i to declare environment variable name PYTHONPATH ? the Maya scripts directory is the one in My documents/Maya/…? What version of Python? 3.2?.

Hello.I install python3.2 and create a environment variable name PYTHONPATH (my documents\maya\2011-x64\script . Then i put your __init__ file in it, and put the file cvShapeInverter in Maya\2011\bin\plug-ins\ directory. I can see and load the cvShapeInverter.py plugin in the Plug-in Manager.
I first select the original skinned model, shift select the corrected model and run:
import cvShapeInverter
cvShapeInverter.invert()

Maya tell me:
# Error: AttributeError: ‘module’ object has no attribute ‘invert’ #

Hi Chad,
Cheers for this, an AMAZING helping hand it is. Only one problem…I can’t seem to get it working properly. When I select the skin mesh and shift-select the sculpted mesh and run the ocmmand, this is what I get :
# Error: ValueError: More than one object matches name: pasted__pasted__pasted__polySurfaceShape1 #

You have to make sure your scripts directory is in your Python path.
