In that 50-link chain, is each link a separate Poser part? If so, I wouldn't want to have to find disk space for it with all the space-wasting rhubarb of umpteen CR2 "channels" at each joint, or to have to face a python-wrestling exercise every time I pose it. My flamethrower model's fuel hose and gun has 9 parts, and posing that is enough for me. It would be useful if a long thin object could be ONE part, and could follow a route calculated by fitting cubic splines to a list of positions (and attitudes at those positions) specified by the user.
