Messing with one part of the body/item may or it can fuck other parts.. it's better to start with lower values on most of the times you don't need higher ones anyway.. plus it will reload the the outfit everytime you move the figure even if it's the finger.. higher value - higher load..It is useless to put at 100 since we have to find the right number, and the best way not to put in pls the pc is to play also with the collision.
It is better to be precise than brutal with smoothing.
