Quote - I was thinking  that if I could get one of my riggs to work on them without changing any of their body groups then I could put out a rigg for them.  Otherwise there would be no way to do it without also including the geometry.

If you change the grouping you can distribute the work as a difference file using the free Objaction Mover or RTEncoder for encoding to the original... a simple one-click operation.

UVmapper Classic which is free can export the grouping in a distributable .uvs file I think.

There may even be a way to do this as an injection pose.
