The best way to make a cloth in Rapier?

[trusktr]

What's the best way to make a cloth with Rapier? The one in the joints example (the grid of spheres) seems to rigid, as in the joints mostly only bend like hinges, i.e. when the cloth is hanging almost motionless, a force that is paralellel with the cloth, to the left or right of the cloth, does not seem to make the spheres move left/right (i.e. the grid cells remain mostly square, not more freely turning into parallelograms).
