:o “Oooh, that looks painful!”
My poor, long-suffering mannequin’s feet were literally twisted, with the arch about 90-degrees one way and the toe 90-degrees to the other. Looked a bit like some kid had left one of his little-green-men out in th sun (on purpose) and then gave it a double-twist on the old tarsals.
Turns out that the problem was an interesting one. You have to use a Locked Track constraint to keep the foot from twisting…
