I'm using Apple Motion for the first time in production context for a movie. We're adding snow and mist particles to certain shots. My main concern while working with motion is that every time I change a parameter, Motion processes the whole particle layer to display it again. Is there a way to stop this "dynamic" behavior of the interface to be able to change many settings and then ask for an update? In the same fashion as the Always/Manual update button in Shake. Many thanks!
