@Writers Sub-d will increase the number of springs. But in Poser I think it doesn't change because the sub d is only on render (not sure!) with DS plug it's the subdivised object that is used in VWD

@VWD: what's the best combination for result. Less vertices and low distance min or more vertices and higher distance min (0.9)? Or does the distance min has no impact on quality simulation so the number of vertices is the more important
