Get skincluster data with Maya ' s Python API

The code below demonstrates, via Maya ' s Python API, how to retrieve:
–mobject from a mesh, and its skincluster
–mfnskincluster for the skincluster on that mesh
, haven influences in that skin cluster and their names
, Haven influence weights for every vert on that mesh
enjoy!

##  Don ' t mind the short names, I had a habit of using MC, OM, OMA for Maya ' s modulesI Mport  Maya. Openmaya as Omimport maya. Openmayaanim as Oma

Next, we'll get the Mobject & Mdagpath for our mesh ' s ShapeNode

# The shape node for some mesh ' PSphereShape1 '  == om. Mobject () meshdagpath  = om. Mdagpath () msel.getdependnode (0, Meshmobject) msel.getdagpath (0, Meshdagpath)

Next, an mdagpatharray of the influences and the influence count.
Also, the node names for those influences, for convenience.

# Influences & influence Countinfluences== skinfn.influenceobjects (influences)#  Get node names for influences for in range (Infcount)]

Finally, get all of the weight data, organized as a dictionary of dictionaries.
The first level would use vert indices for keys, the next would be a dict of influence name:weight.

Weightdata = {}#Ordered by Vertiter 0-numvertsVertiter =om. Mitgeometry (Meshmobject) while  notVertiter.isdone (): Vertinfcount=om. Mscriptutil () vertinfcountptr=vertinfcount.asuintptr () om. Mscriptutil.setuint (vertinfcountptr, 0) weights=om. Mdoublearray () skinfn.getweights (Meshdagpath, Vertiter.currentitem (), weigh TS, vertinfcountptr)#Create A dictionary for each vert index in the mesh    #All influences'll is returned for each vert and may have 0 influenceWeightdata[vertiter.index ()] =dict (Zip (influencenames, weights)) Vertiter.next ()
