I got the M4 Walk designer which is not very good.
The V4 and M4 “Walk designers” are for use in Poser’s “Walk designer” which allows you to Mix elements of the different included 30 frame animations to create your own walk for that figure,. and they work well.
Daz Studio doesn’t have “Walk designer”,. so all you can do is load the pre-set “30 frame animations”,. not mix them together to create a new walk based on a percentage of influence from each selected animation, and make the animation as long as you require or follow a path you create..
Hope it helps
