How do you scale cloth simulations? I can't figure out what exactly to do with this, when I run the simulation at a smaller scale, everything is fine. 



When I scale it by 10 it becomes strange, even though everything is aligned with the origin and the force field is a point and as such scale shouldn't affect it.



Which parameters need to be modified for it to scale correctly?
To get your simulation to work efficiently, you must first, save your .blend file, then bake the simulation. The bake settings are under the cache tab in the cloth settings. You will be able to scale it to whatever then.
