Solved a potential problem, alas the solution is an old utility that cannot be downloaded.

To solve the symmetry problem:

Export the bodypart (or whatever) following the instructions in this thread.

Follow the instructions for importing in to Sculptris. Do not bother with symmetry.

Work on one side (a small bit of overlap is ok)

Export out of Sculptris as directed.

Now what to do? Dig deep in your Poser file backups (around 2003 or so lol!) and try to find MT Mirror II!

If you had signed up to the old PoserPros site, this link will give you more details onm working with MT Mirror II. (Links, alas are busted)

Apparently this works for me, YMMV.
