Judah: sorry, I still didn't test it out... just made a quick run on the
docs to check that script support thingy. Anyone tried clicking the obsolete
node's "see the other method" link to get into the same method? Maya docs
2009/2010 have some kind of error maybe? Anyhow, I'll give it a try using
the callback later!
Dado: this doesn't work as my node doesn't have a transform. Recursively, I
tried getting the node's name through a selection list:
#this code goes into postConstructor
selList = OpenMaya.MSelectionList()
selList.add(self.thisMObject())
lista = []
selList.getSelectionStrings(lista)
print 'Node name =', lista[0]
...with no success, still doesn't print out the node's name! :(
Thanks for all your help guys!
