I have just added a simple air pressure feature to Blender cloth simulator, and spring length scaling factor, hope it will be useful for somebody See screenshots:
And there is a YouTube video demostrates this feature (warning, a bit outdated):
but I’m afraid that new users can’t post link… Anyway, if you google “blender cloth pressure” then you can find my video easily…
And there is a patch against svn r45571:

Finally I have a question: My code added a new property “spring length scaling” to Cloth modifier, whose default value is 1.0. But when I open old blend files contain Cloth simulation, the property is loaded as 0.0, breaks the simulation What should I do to let the program load the default value correctly if old blend file doesn’t contain this property?
