so I have a Softbody actor that I want to reset completely to it's initial state.
Currently I'm caching the particle position, orientation, velocity and angular velocity and applying these values on reset.
This mostly works. However, the permanent softbody deformation is not reset, so it stays squished.

Can I cache the initial deformation (no deformation at all) as well or is there another approach I have to take?
I'd rather not instantiate a new actor, I would prefer to reset the existing one if possible.

You could set the plastic recovery parameter to a high value, so that the deformation matrices are reset at the end of the first simulation step after resetting the softbody.

In the future we will consider exposing the deformation tensors trough the API.

I think having API access would be greatly appreciated, considering the API doesn't offer that many high-level methods (such as Reset).

Nevertheless, I'm very happy with the Plugin, keep up the good work.
