okay I did that by putting cloth tag to a sphere ( low res, editable and without phong tag) then I’ve duplicate my sphere (with the cloth tag) and put it into an atom array and voila !you can change the cloth tag’s settings but they must be the same for the two spheres.Then if you put a collision (modyn) tag to the first sphere and to a cloner objet (with an object inside of course), and a ground with a collision (modyn) and cloth collision you gonna have that you want !
