Static structural elements during interaction can fall to the ground and become static objects again without losing their shape, an explosion can interact with structural elements (wooden house planks can fall in different directions and become static again after a certain time), will give reality and more interactivity with the world (probably not harm performance
)
Fire system, wooden materials burn over time changing their texture on a burnt tree, also falling to the surface so that a mountain of static burned garbage remains from the house.
