This seems to strengthen my thesis. WorldVertex(5) of the slave actor in my figure returns different coordinates, depending on classic vs unimesh skinning.

 

wg = poser.Scene().CurrentActor().WeldGoals()
print wg
[[-1, -1, -1, 3, 4, 5, -1, -1, -1, -1, -1, 11, 12, -1, -1, -1, -1, -1, -1, -1, 20, 21, -1, -1, -1, -1, -1, 27, 28, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1]]

Vertex 5 is chosen because it has a weldgoal.

Based on this output and the unwelded preview frame in the picture I suspect WorldVertex() is not returning the truth when unimesh skinning is active (assuming, the welded position should be the world vertex coordinate).

So I indeed guess, PML should be used with classic skinning.

P.S. Subdivision is still fine.
