That script is more tedious than clever 8( however it does save all the cloth parameters. It should be possible to extend it to save the simulation detail by name, cloth object, collision objects etc BUT you can just save the scene (pz3) and get all that. I wrote the thing so if I had a nice tablecloth , or scarf, etc I could save the values for another object and not have to keep writing stuff down.

For the script to work you need a scene with only 1 sim defined. It will load the cloth parameters into that sim.
