No. I meant chains of metal links in as e.g. dockside crane. But as regards a "cocoon suit", if that means adapting a figure by moving each vertex out along its normal by a set amount to produce the effect of a thick rubber suit, well, I had the same when making my Gerry Anderson UFO alien in a spacesuit model to allow for thickness of spacesuit and undersuit, and the only place where I found significant misbehavior was between his thighs when I stood him with his legs apart, and I cured that by switching the relevant joint parameter off (the one that is defined by the big red and green loops). I had the same to less amount with my "man in diving suit" model.
