I did wonder whether you could access that point order to build a standin mesh, before finding out the cage deformer was a much simpler way to go.
Its an old rig built by someone else which uses a lattice enveloped to nulls to deform a pack, and I've been trying to find a way to paint the weights on the lattice and smooth them out (pack logo was deforming too much in places) - using a mesh I could smooth weights and cage deform the lattice.
