Sorry for the late response guys, a good soft-body physics engine doesn’t implement itself!
@, and others: technically, anything you can simulate with masses and springs can be done with our plugin.
@n00854180t: Right now, only entire meshes can be turned into soft objects. We are in the process of implementing a way to select a part of a mesh/character to turn into a soft object. It is essential in creating a plugin that is easy to use and at the same time versatile enough to be used for pretty much anything you would want to.
@OnfireNFS: The lack of posts and updates is because we are very busy with development 
How do you see the combination of APEX (now PhysX) and our plugin? Since PhysX is built into the Unreal engine, we are implementing our plugin in such a way that it can interact with PhsyX objects as you could see in the video of the rolling ball demo. But is there anything specific that you have in mind?
Again, any ideas and suggestions are welcome because they will contribute to a better plugin.
