Rigging and Corrective Shapes

[Ramteen]

Hello guys, I know that this question's been asked before (similar).

Can anyone guide me how it's possible to setup a corrective shape workflow so the corrections happens before capture deformation?

Problem with Post-Deformation corrective shapes is that they work well as long as the character hasn't changed orientation, Say the global rotation of the character. Try that and the corrective shapes simply break down.

So one solid and proven solution would be extracting the corrective shapes ,So they can be fed into a "Blendshape SOP" before the "CaptureGeometry SOP" does its thing.  (Equivalent Maya tools:  Extract Delta, cvShapeInverter, etc...)

Has anyone figured a way around this problem?

 

Thanks in advance

have a look at the sopcreteedit command

Thank you so so so much Michael. 

Using the -d flag was the key to solving this issue. 

I tried the method, and it really worked!!! Here's the command used to solve it:

 

opcd /obj/tube_object1/

sopcreateedit -d diff deform   edit

 

Beautiful

we should really make that one easier to find

it's super powerful/important but often overlooked.

Absolutely, What impresses me is that Houdini's had this feature built in while a similar solution had to be coded in Maya!
