Thanks for your reply Paul.
Did you mean getAliasList instead of getAliasAttr, right? With this option
I get a list with the aliases, but the names of the attributes are included
too:
import maya.OpenMaya as om
list = om.MSelectionList()
node = om.MObject()
list.add("blendShape1")
list.getDependNode(0, node)
dgNode = om.MFnDependencyNode(node)
aliasList = []
dgNode.getAliasList(aliasList)
# Result: [u'pSphere2', u'weight[0]', u'pSphere3', u'weight[1]'] #
I don't understand the MSelectionList combo, could you explain it please?
Thank you Paul.
