See the inputComponents attribute of the polyChip node.
cmds.getAttr("polyChip1.inputComponents")# Result: [u'f[202]',
u'f[239]', u'f[241]'] #
*Example*
sphere, _ = cmds.polySphere()
cmds.select(
sphere + ".f[202]",
sphere + ".f[239]",
sphere + ".f[241]"
)
chip = cmds.polyChipOff()
faces = cmds.getAttr(chip[0] + ".inputComponents")
cmds.select(
sphere + "." + faces[0],
sphere + "." + faces[1],
sphere + "." + faces[2]
)
Normally, components affected by polygon modifications - like soft
modification, skinning, extrude etc - are stored in an invisible objectSet
node, which I was looking for at first. But as it didn’t have any, I knew
it must have been stored internally. In this case, it looks to be a
compound string attribute.
