Also, the joints of Poser figures' thumbs need seeing to. If I stand in the standard T-shaped Poser human attitude, most of my joints are arranged in one of the 6 xyz attitudes, but my thumb joints are not, and I find that adjusting Poser thumb joints with the parameter dials makes them behave as if the joints were deformed. I suggest that the Poser humans' thumbs' joints rotation axes need to be rotated away from the xyz direction. Setting Poser joints askew to the xyz axes can be done :: I did it with my Gerry Anderson UFO alien's helmet-on-neckseal rotation joint.
