I have created four objects using soft bodies to simulate cloth which are being affected by force fields (wind) but two are behaving abnormally and I do not know why.
I have posted images (click for more) which show the result of animation and also the settings I have used. I am using constraints to hold the soft body cloth to another mesh, and the soft body cloth also has a wave modifier on it as well.
During the animation process two of the soft body meshes (sail) comes away from the mast. while the other two do not. You can see all of this in the images that I have posted.
