particles - initial state

Создаю значит партиклы. Симулирую, потом сохраняю initial state через менюшку Solvers - Initial State - Set for selected. А вопрос в том, как собственно от этого начального состояния потом можно избавиться?
Можно ли очистить кэш партиклов, чтобы они вели себя как при создании эмитера?
