Cage,

Quote - I'm testing the pose mixer script.  It does do a very good job of correcting the positioning of the limbs, but there's trouble with the feet sliding.  I think Les noted that before, when working on it.  I think that might have something to do with the differing twist angles between the P4 source figure and Antonia, but I'm not sure.    Of course, there seems to be some foot sliding in Posette, too....

Yes I think there was a problem with the feet sliding. There are two kinds of sliding, side-side is one, or the BODY moving forwards at a different rate than the feet (which I think is called "skating"), so that the foot that should be planted, is sliding forwards or backwards over the ground. I think it was this skating that was the big problem, but there may also have been a bit of side-side sliding. It may be due to twist angles, there again it may be related to differences in leg length between Antonia and P4 figures, or the proportionality between thigh length and shin length. Have you noticed these parameters in the Poser walk files?

thighLength 0.213434
feetDistance 0.045139
hipHeight     0.405027

I think the last two were added in P6, I certainly don't remember them in P4, though thighLength was there.
