Hey Guys, haven't done much with blender in the last couple of weeks but I played with NLA strips today with some success. I got a little frustrated the last couple of times I played with NLA in blender so the progress was nice.
I used the separate NLA strips for the walk cycle, moving him forward, turning his head, clenching left hand and moving his right hand to his face. I found out how to scale, duplicate, move and transition Strips but don't know how to overlay strips smoothly, blender seems to totally override the NLA strips sometimes. More learning is required.....
