Keeping shape work in similar way, it the rod is stiff it bends very fast to target shape, but making it softer results in very slow "lerp like" change of rotation.
The thing is I want my rod to be overall soft enough, but at the same time change shape reasonably fast.
Material models can't really distinguish between internal and external forces - the former cause elastic materials to return to their "rest" shape, and the latter deform the object due to collisions, manipulation, etc: they react to all forces equally.
Because of this, it is simply not possible (or at least, not possible if you want to be physically accurate) to make an object that is easily deformed by external forces but returns to its plastic rest shape very fast - as it would essentially mean has different mass depending on the kind of force it's subjected to.
kind regards,
