Re: [Script] Point Position of Enveloped Object in Shape Modeling stack

[Raffaele Fragapane <jaco(at)thejaco.com>]

all you need is to get the positionarray after the enveloping, multiply 
each vector for the transformation of the object to get its global 
equivalent and then dump these coordinates anywhere you want, which 
might even be a copy of your object.
once you have that you can use the copy of your object as a shape target
