...there are about 25 'walk types' when using Nerds walk designer. I think Poser comes with a good 15'ish or so by itself if I remember right. Not sure. There are also six "tweaks": Head Bounce, Arm Swing, Arm Out, Hip Swing, Leg Lift, and Stride. I should have mentioned too that you can choose any combination of any walk types you like, i.e. 25% P4 run, 42% strut using negative percentages if ya like, and then tack on whatever combination of tweaks you choose.
