Quote - If a special figure is used and the instep actors remain rigid, maybe it's possible to just combine foot and instep for this "WD-Antonia", so that no point pushing or extra adjustment will be needed? If I understand correctly, the output of WD will simply be an animated pose, so if the instep actor is not mentioned in that, no harm will be done.

That's correct.  We'd generate an animation which will have the actors re-named, for use of Proper Antonia.

If the instep actors include the right portion of the foot geometry and my guess about what's happening is correct, merging the foot and instep seems like it would do the trick.

But we'll have to distribute these poses somehow, too.  I don't think we can distribute poses which are derived from the P4 walk cycles, can we?  If not, we'll need to encode them,  or something.  But I notice that Poser 8 doesn't include the P4 animations.  So how can we distribute these walk cycles?

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
