How could you prove that any particular weight map was produced by a scripted conversion? Its a no brainer to add code to apply a small random factor to each weight. Unless you knew what that factor was you could never prove where its source came from. Then if the user takes that as their starting point and made a few minor adjustments .......... "tweaking those weights" ...... would, in my opinion, have been achieved.

I do however accept that the weight map data must be injected into the figure.
