First of all I want to start with what I already know. 

In iclone motion director performance and mixer files can be added, replaced or removed. Also any of them can be edited in the timeline. 

What I want to learn is that I've downloaded a walking motion file from mixamo and I really liked its walking style. I want my character walk like that when I start motion director. 

Now I need to find a way to manage it so I need your help. 

Have a nice day
