This is for P5 but I suppose it is also related to P4: 1.)load Don 2.)create walk path 3.)straighten walk path so it's a straight line 4.)apply run at 80% The shins will jerk just like Tim's animation does. Now go back to the WD and change the number of frames from the default 120 to 80-90 frames. Your walk path length will have some effect on the number you need here. Apply it. The animation is now fine. No jerking shins or feet. Poser doesn't have any math logarithms to calculate path length and compare them to the preset cyles or the percentages you set them at. You have to be able to see that on your own and know whether to add or subtract total key frames so they match. ScottA
