Here is a comparison of standard Antonia 1.0.0 (no forced forced limits) superimposed in outline, on Antonia-1.0.1, WW test version (with forced translation limits). Note that the top of the head is generally at a lower altitude in the standard version and bobs up and down, this is due to yTranslations of the hip. I ran the Walk Designer with the default settings, no blends applied. The path is straight. The animation is 29 frames, then loops, it runs slowly at 120 fps to give you a chance to see what is happening. The camera is following the figure along the path.
