thanks thats helpful, actions on paths then from a to b.
so basically in a big screen animation most of the main movement around a scene will be characters on paths?
there'd be one main entrance/exit path and all the jumping around,scratching the butt and gesticulating would be away from that path.
like for instance 'character(walks into room) constrained to path until frame.. then unconstrained,moves to the left a few metres, scratches butt, does a quick twirl, and then back to path, constrained back to path, walks off screen.? throughout which the model bone is not touched.
